Post common envelope binaries (PCEBs) consisting of a white dwarf and a main sequence star are ideal systems to calibrate current theories of angular momentum...

Identifying new white dwarfs (WDs) heavy elements is crucial, as they serve as valuable tools for deducing the chemical characteristics of potential planetary...

In this poster, we present the project that will survey all white dwarf stars observed in the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) and the...

White dwarfs are the evolutionary end point of the vast majority of stars (97 per cent),where a large fraction of systems, around 25 per cent, are close enough...

We have created a new and unique database, the APOGEE-Galaxy Evolution Explorer (GALEX)-Gaia catalog, to study white dwarfs in close binaries, and, in...

We present accurate and deep multiband B,R,Hα data for the globular cluster ω Cen collected with the Advanced Camera for Surveys on HST. The photometric...

The infrared excess shown by white dwarfs can be an indicator of a low-mass substellar companion, like a brown dwarf or even an exoplanet. In this work, we...

We present the main results derived from a chemical analysis carried out on a large sample of galactic O-rich AGB stars using high resolution optical...
