Star complexes and stellar populations in NGC 6822 - Comparison with the Magellanic Clouds

TL;DR: In this article, the star complexes of NGC 6822 were determined by using the isopleths, based on star counts, of the young stars of the galaxy, using a statistical cutoff limit in density.
Journal ArticleDOI

Gaia Data Release 3: Stellar multiplicity, a teaser for the hidden treasure

Gaia Collaboration F. Arenou, +448 more
TL;DR: The Gaia DR3 Catalogue as mentioned in this paper contains about eight hundred thousand solutions with either orbital elements or trend parameters for astrometric, spectroscopic and eclipsing binaries, and combinations of them.
Journal ArticleDOI

International observational campaigns of the last two eclipses in EE Cephei: 2003 and 2008/9

TL;DR: In this article, two blue maxima in the colour indices were detected during these two eclipses, one before and one after the photometric minimum, and the first (stronger) blue maximum is simultaneous with a "bump" that is very clear in all the UBVRI light curves.
Journal ArticleDOI

Gaia Data Release 3. Apsis II: Stellar parameters

TL;DR: In this article , the Apsis pipeline was developed to infer stellar astrophysical parameters (APs) from the Gaia prism spectra (BP and RP) and the spectrograph (RVS).
Journal ArticleDOI

Gaia Data Release 3. Mapping the asymmetric disc of the Milky Way

Gaia Collaboration R. Drimmel, +454 more
TL;DR: In this article , the authors select various stellar populations to explore and identify non-axisymmetric features in the disc of the Milky Way in both configuration and velocity space using the Gaia DR3 data.
