Description:
The VSOP (VLBI Space Observatory Programme) mission was led by the Institute of Space and Astronautical Science, in collaboration with the National Astronomical Observatory of Japan with international collaboration with NSAS, CSA, JIVE and the world radio telescopes in 14 countries. This mission provided a dedicated space radio telescope "HALCA" launched in February 1997, and carried out high-resolution observations at 1.6, 5.0, and 22 GHz with ground radio observatories to perform Very Long Baseline Interferometry (VLBI) on baselines of up to 2.6 Earth diameters. The observations are continued till 2003, and HALCA finished its operation in 2005.

Description:
This table records high-level information for the observations obtained with Hitomi. Hitomi was equipped with four different instruments that together cover a wide energy range 0.3-600 keV. Data were collected from six celestial objects (Perseus, N132D, IGR_J16318-4848, RXJ1856.5-3754, G21.5-0.9, and Crab) as well as black sky for a total of about one month of data in 2016.

Publisher:
JVO
Description:
IThe Japanese satellite-borne infrared telescope, the Infrared Telescope in Space (IRTS), surveyed about 7 per-cent of the entire sky in the infrared wavelengths from 1.4 to 700 um. The IRTS consists of a 15 cm telescope cooled with superfluid liquid helium, and is installed on board the Space Flyer Unit (SFU) spacecraft. The SFU was launched on 1995 March 18 UT. The sky survey by the IRTS started on March 29 UT, and was completed on April 25 UT after exhausting its liquid helium. The four focal-plane instruments were on board. The Mid-Infrared Spectrometer (MIRS) covered 4.5 to 11.7 um by 32 spectral channels with the resolution of Δλ = 0.23-0.36 um. The MIRS point source catalog contains spectra of 536 sources. Many of the detected sources are mas-losing stars. A few HII regions and one asteroid 01 Ceres are included.

The sky survey by the IRTS started on March 29 UT, and was completed on April 25 UT after exhausting its liquid helium. The four focal-plane instruments were on board. The Near-Infrared Spectrometer (NIRS) covered 1.4 to 4.0 μm by 24 spectral channels with the resolution of Δλ = 0.13 μm. The complete level of the catalog is 10?20 Jy for the entire wavelength range. The NIRS point source catalog contains spectra of 14,223 sources in which 4,002 sources are in good quality. Late-type stars, normal stars, and other red objects are included.

SAGA -Stellar Abundances for Galactic Archeology Database-
Short Name:

Description:
We describe the construction of a database of extremely metal-poor (EMP) stars in the Galactic halo whose elemental abundances have been determined. Our database contains detailed elemental abundances, reported equivalent widths, atmospheric parameters, photometry, and binarity status, compiled from papers in the recent literature that report studies of EMP halo stars with [Fe/H] < -2.5. The compilation procedures for this database have been designed to assemble the data effectively from electronic tables available from online journals. We have also developed a data retrieval system that enables data searches by various criteria, and permits the user to explore relationships between the stored variables graphically. Currently, our sample includes 1212 unique stars (many of which are studied by more than one group) with more than 15000 individual reported elemental abundances, covering all of the relevant papers published by December 2007. We discuss the global characteristics of the present database, as revealed by the EMP stars observed to date. For stars with [Fe/H] < -2.5, the number of giants with reported abundances is larger than that of dwarfs by a factor of two. The fraction of carbon-rich stars (among the sample for which the carbon abundance is reported) amount to ~30 % for [Fe/H] < -2.5. We find that known binaries exhibit different distributions of orbital period, according to whether they are giants or dwarfs, and also as a function of metallicity, although the total sample of such stars is still quite small.
