  "abstract": "Hot stars, of spectral types O-, B-, and A-, represent a small fraction of the stars observed by the Gaia satellite. Their properties and the specifications of the on-board instruments make their identification challenging. In the Gaia DR3, 12, 104,577 targets have been assigned a temperature greater than 7500 K. It represents about 2.5 percent of the stars having an effective temperature value in the Gaia DR3 astrophysical parameters table. We review the results obtained by the Apsis modules, focusing on the effective temperature, surface gravity, interstellar extinction, and V sin i parameters.",
