This data server provides access to the ALHAMBRA Final Catalogue. The ALHAMBRA (Advance Large Homogeneous Area Medium Band Redshift Astronomical) survey (Moles et al. 2008) has observed 8 different regions of the sky, including sections of the COSMOS, DEEP2, ELAIS, GOODS-N, SDSS and Groth fields using a new photometric system with 20 contiguous, non-overlapping, equal width (~ 300A) filters, covering the optical range (3500A-9700A), plus the standard broadband NIR J, H and Ks filters. The observations were carried out with the Calar Alto (CAHA) 3.5m telescope using the wide field, 0.25 deg2 FOV optical camera LAICA and the NIR instrument Omega-2000. The ALHAMBRA survey dataset represents a ~700hrs of total exposure time, gathered in between the 2005 and 2012.Further information on the project can be found at the ALHAMBRA web page.
CMC15 is an astrometric and photometric catalogue of more than 122.7 million stars in the magnitude range 9 < r' (SDSS) < 17. With a positional accuracy to about 35 mas, the catalogue covers the declination range -40deg to 50deg. The current release comprises all the observations made between March 1999 and March 2011. The catalogue fills the gap between 5h 30m and 10h 30m for declinations south of -15deg of the CMC14 and adds the bans -30deg to -40deg. Some zones north of -30deg have also been re-observed in order to improve their internal errors.
Planetary systems are built by planets and planetesimals formed in
circumstellar disks surrounding young pre-main sequence stars. Once in
the main-sequence collisions of planetesimals produce small dust
particles giving rise to the so-called debris disks. The mutual
interaction among planets, planetesimals and debris disks, and with
their host stars determines the fate of planetary systems.
Currently thousands of main-sequence stars are known to host planets and
debris disks. The Solar System with its peculiarities is just one of
such planetary systems. However, only few tens of stars are known to
host simultaneously both planets and debris disks. Therefore, the
study of those systems is particularly valuable to widen our knowledge
of planetary systems and their evolution.
This page just collects some of the properties of the known, to our knowledge,
solar-type stars hosting both planets and debris disk.
