- Description:
- We present numerically derived orbits and mass estimates for the inner Saturnian satellites, Atlas, Prometheus, Pandora, Janus, and Epimetheus from a fit to 2580 new Cassini Imaging Science Subsystem astrometric observations spanning 2004 February to 2013 August. The observations are provided as machine-readable and Virtual Observatory tables. We estimate GM_Atlas_=(0.384+/-0.001)x10^-3^km^3^/s^2^, a value 13% smaller than the previously published estimate but with an order of magnitude reduction in the uncertainty. We also find GM_Prometheus_=(10.677+/-0.006)x10^-3^km^3^/s^2^, GM_Pandora_=(9.133+/-0.009)x10^-3^km^3^/s^2^, GM_Janus_=(126.51+/-0.03)x10^-3^km^3^/s^2^, and GM_Epimetheus_=(35.110+/-0.009)x10^-3^km^3^/s^2^, consistent with previously published values, but also with significant reductions in uncertainties. We show that Atlas is currently librating in both the 54:53 co-rotation-eccentricity resonance (CER) and the 54:53 inner Lindblad (ILR) resonance with Prometheus, making it the latest example of a coupled CER-ILR system, in common with the Saturnian satellites Anthe, Aegaeon, and Methone, and possibly Neptune's ring arcs. We further demonstrate that Atlas's orbit is chaotic, with a Lyapunov time of ~10years, and show that its chaotic behavior is a direct consequence of the coupled resonant interaction with Prometheus, rather than being an indirect effect of the known chaotic interaction between Prometheus and Pandora. We provide an updated analysis of the second-order resonant perturbations involving Prometheus, Pandora, and Epimetheus based on the new observations, showing that these resonant arguments are librating only when Epimetheus is the innermost of the co-orbital pair, Janus and Epimetheus. We also find evidence that the known chaotic changes in the orbits of Prometheus and Pandora are not confined to times of apse anti-alignment.

- Description:
- This compilation contains the current content (as of 1 September 1993) of the Catalogue of cataclysmic binaries, low-mass X-ray binaries and related objects (previous version: A&AS 85, 1179, catalogue <V/59>) Please refer to the introduction (file "intro.tex") for a more complete introduction.

- Short Name:

- Date:

- Publisher:
- CDS
- Description:
- Cataclysmic Binaries are semi-detached binaries consisting of a white dwarf or a white dwarf precursor primary and a low-mass secondary which is filling its critical Roche lobe. The secondary is not necessarily unevolved, it may even be a highly evolved star as for example in the case of the AM CVn-type stars. Low-Mass X-Ray Binaries are semi-detached binaries consisting of either a neutron star or a black hole primary, and a low-mass secondary which is filling its critical Roche lobe. Related Objects are detached binaries consisting of either a white dwarf or a white dwarf precursor primary and of a low-mass secondary. The secondary may also be a highly evolved star. The catalogue lists coordinates, apparent magnitudes, orbital parameters, stellar parameters of the components and other characteristic properties of 318 cataclysmic binaries, 47 low-mass X-ray binaries and 49 related objects with known or suspected orbital periods together with a comprehensive selection of the relevant recent literature. In addition the catalogue contains a list of references to published finding charts for 394 of the 414 objects. A cross-reference list of alias object designations concludes the catalogue. Literature published before 30 June 1997 has, as far as possible, been taken into account. This catalogue supersedes the 5th edition (catalogue <V/59>) and the updated list by Ritter and Kolb (1995; catalogue <V/82>).

- Cataclysmic Variables Catalog (2006 Final Edition)
- Short Name:
- CVs
- Date:

- Publisher:
- NASA/GSFC HEASARC
- Description:
- This catalog contains data for a large number of objects that have been classified as cataclysmic variables (CVs) as well as a smaller number of objects that are now not considered to be cataclysmic variables, but were originally classified erroneously as such. As of 2000 December, 40% of the objects in this catalog were dwarf novae, with another 30% being novae, and the rest being mostly nova-like variables; also as of this date, a large fraction (90%) of the CVs had references to published finding charts, while 64% of the objects had published spectra. The catalog includes coordinates measured in the reference frame of the Hubble Space Telescope Guide Star Survey for non-novae and from the literature for novae. Also given are the variability type, the magnitude range, orbital periods, flags indicating the existence of relevant space-based observational datsets, references to finding charts and spectroscopy, the galactic latitude and longitude, and the year of outburst (for novae). This edition also includes plate identification information for the coordinate measurements, and a reference to the classification. The Catalog and Atlas of Cataclysmic Variables (Downes et al. in 2001, PASP, 113, 764 and <a href="http://archive.stsci.edu/prepds/cvcat/">http://archive.stsci.edu/prepds/cvcat/</a>) presented here is the ASCII Report mentioned in Section 2.1 of the PASP paper, and is similar to the previously published versions of the CV Catalog (e.g., Downes, Webbink and Shara 1997, PASP, 109, 345, Table 1). The online version of the CV Catalog at <a href="http://archive.stsci.edu/prepds/cvcat/">http://archive.stsci.edu/prepds/cvcat/</a> contains additional data on these systems not included in this database, including finding charts. For a complete authoritative and up-to-date description of the CV Catalog, refer to <a href="http://archive.stsci.edu/prepds/cvcat/description.html">http://archive.stsci.edu/prepds/cvcat/description.html</a>, from which the HEASARC has constructed this help file.

- Cataclysmic variables from CRTS
- Short Name:
- J/MNRAS/441/1186
- Date:

- Publisher:
- CDS
- Description:
- We present 855 cataclysmic variable candidates detected by the Catalina Real-time Transient Survey (CRTS) of which at least 137 have been spectroscopically confirmed and 705 are new discoveries. The sources were identified from the analysis of five years of data, and come from an area covering three quarters of the sky. We study the amplitude distribution of the dwarf novae cataclysmic variables (CVs) discovered by CRTS during outburst, and find that in quiescence they are typically 2mag fainter compared to the spectroscopic CV sample identified by the Sloan Digital Sky Survey. However, almost all CRTS CVs in the SDSS footprint have ugriz photometry. We analyse the spatial distribution of the CVs and find evidence that many of the systems lie at scale heights beyond those expected for a Galactic thin disc population. We compare the outburst rates of newly discovered CRTS CVs with the previously known CV population, and find no evidence for a difference between them. However, we find significant evidence for a systematic difference in orbital period distribution. We discuss the CVs found below the orbital period minimum and argue that many more are yet to be identified among the full CRTS CV sample. We cross-match the CVs with archival X-ray catalogues and find that most of the systems are dwarf novae rather than magnetic CVs.

- Publisher:

- Description:
- Big data in the form of stellar spectra from the spectroscopic survey associated with the Large Sky Area Multi-object Fiber Spectroscopic Telescope (LAMOST) are important for studying properties of cataclysmic variables (CVs). By cross matching the catalogs of CVs compiled with LAMOST DR3, acquired from October 2011 to July 2015, we obtained the first spectroscopic catalog for CVs observed by LAMOST with high signal to noise ratio, above 8. By integrating line profiles, their equivalent widths (EWs) of the H{alpha}, H{beta}, H{gamma} and H{delta}, as well as HeI 5876 and 6678{AA} lines, were calculated. There were 74 stellar spectra from 48 known CVs and three spectra from three new CV candidates. At the same time, we also collected their previously published EWs. Thirty-three objects had repeated spectra and 30 stars showed spectral variability in the H{alpha} line. Moreover, we carried out photometric follow-up studies for five CVs (UU Aqr, TT Tri, PX And, BP Lyn and RW Tri). We obtained nine new light curves and revised their linear ephemerides. For RW Tri, there is a possible oscillation with an amplitude of 0.0031(2) days and a period of 47.6+/-0.4 years, which might be caused by a third body (brown dwarf) or magnetic activity cycle.
