The Pristine Inner Galaxy Survey (PIGS) VI: Different vertical distributions between two DIBs at 442.8 nm and 862.1 nm
He Zhao, Mathias Schultheis, Anke Arentsen +8
Although diffuse interstellar bands (DIBs) were discovered over 100 years ago, for most of them, their origins are still unknown. Investigation on the correlations between differen…

L. Delchambre, C. A. L. Bailer-Jones, I. Bellas-Velidis +78
Context. As part of the third Gaia data release, we present the contributions of the non-stellar and classification modules from the eighth coordination unit (CU8) of the Data Proc…
Stellar ages, masses, extinctions and orbital parameters based on spectroscopic parameters of Gaia DR3
G. Kordopatis, M. Schultheis, P. J. McMillan +13
Gaia DR3 provides radial velocities for 33 million stars and spectroscopically derived atmospheric parameters for more than five million targets. When combined with the astrometric…
Gaia Data Release 3: Analysis of the Gaia BP/RP spectra using the General Stellar Parameterizer from Photometry
R. Andrae, M. Fouesneau, R. Sordo +80
We present the General Stellar Parameterizer from Photometry (GSP-Phot), which is part of the astrophysical parameters inference system (Apsis). GSP-Phot is designed to produce a h…
Gaia Data Release 3: Apsis II -- Stellar Parameters
M. Fouesneau, Y. Frémat, R. Andrae +78
The third Gaia data release contains, beyond the astrometry and photometry, dispersed light for hundreds of millions of sources from the Gaia prism spectra (BP and RP) and the spec…
