Stars with Debris Disks and Planets:

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.

Images at 70, 100 and 160 micron of the debris disk associated with the solar-type star q1 Eri (Liseau et al. 2010, Astronomy and Astrophysics 518, 132L). The observations were carried out within the Herschel Open Time Key Project DUNES, "DUst around NEarby Stars" (Eiroa et al., 2013, Astronomy and Astrophysics 555A, 11E). q1 Eri is a solar-type F9V star older than around 2 Gyr. It is orbited by a 0.9 M_Jupiter planet at a distance of 2 au. The disk surrounding q1 Eri is about 40 au wide at a radial distance of approximately 85 au, and the fractional luminosity of the dust is of the order of 10-4 solar luminosities.

The Stars with debris disks and planets Data Access Service is the result of a collaboration agreement between the Centro de Astrobiología (CAB, INTA-CSIC) and the Universidad Autónoma de Madrid. It has been developed in the framework of the Spanish Virtual Observatory project supported by the Spanish MINECO through grant AYA 2014-55216, as well as the "Ontherocks project" (AYA 2014-55840-P). The system is maintained by the Data Archive Unit of the CAB (CSIC -INTA).
