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.

This data server provides access to the CMC15 catalogue. 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.

Mark-I is a solar spectrophotometer located and operated at Observatorio del Teide (Tenerife, Canary Islands, Spain) that provides precise radial velocity observations of the Sun-as-a-star at the Potassium KI 7699A absorption solar line. Observations extend from 1976 to 2013 with only summer campaigns from 1976 to 1983.

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.

This data server provides access to 15186 double and multiple star systems found using TGAS data.

This data server provides access to 73,221 white dwarfs identified using Gaia-DR2 and the Virtual Observatory.

This data server provides access to the SVO hot subdwarf catalogue compiled by Pérez-Fernández et al. (2016). It contains 473 hot subdwarf candidates obtained after a photometric and astrometric search in 11663 sq. deg. using GALEX, SDSS SuperCosmos and 2MASS. 86 of these candidates were spectroscopically classified following the classification criteria/scheme in Drilling et al (2013). New potentially binary systems have also been flagged.

This data server provides access to the SVO late-type subdwarf catalogue compiled by Lodieu et al. (2016, submitted). It contains 171 late-type subdwarf candidates obtained after a literature search.

This catalog provides astrometric and photometric information for 277,747 sources included in The 4th Release of the Sloan Digital Sky Survey Moving Object Catalog (MOC4) and linked to known asteroids. Of those, 220,101 come from MOC4 and 57, 646 from a search using the SkyBoT service.
