The SVO archive of hot subdwarfs.

This portal gives access to the following catalogues of hot subdwarfs:

• Solano et al. 2022. A catalogue of 3084 (2469 single + 615 binaries) hot subdwarfs based on Geier et al. (2020) .
• Pérez-Fernández et al. (2016) . A catalogue of 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).

 

The SVO archive of hot subdwarfs is the result of a collaborative effort between the Centro de Astrobiología (CAB, CSIC-INTA) and the Universidade de Vigo. It has been developed in the framework of the Spanish Virtual Observatory (https://svo.cab.inta-csic.es) project funded by MCIN/AEI/10.13039/501100011033/ through grant PID2020-112949GB-I00. The system is maintained by the Data Archive Unit of the CAB (CSIC -INTA).

If you use this service in your research, please include the following acknowledgement in any resulting publications: "Based on data from the SVO hot subdwarf Data Access Service at CAB (CSIC-INTA)".
