A Detailed Spectroscopic Study of the WN6ha + O5 Colliding-wind Binary WR 25

Eric Gosset, Roberto Gamen, Laurent Mahy +3

Massive stars have a major impact on their environment in their host galaxy. Observational determinations of their physical parameters are required to better constrain evolutionary…

The stellar activity-rotation-age relationship under the lens of asteroseismology

C. Pezzotti, J. Bétrisey, G. Buldgen +6

In low-mass stars, the connection between magnetic activity, rotation period, and age provides key insights into the functioning of dynamos. Fully understanding the activity-rotati…

Gaia Focused Product Release: Sources from Service Interface Function image analysis -- Half a million new sources in omega Centauri

Gaia Collaboration, K. Weingrill, A. Mints +400

Gaia's readout window strategy is challenged by very dense fields in the sky. Therefore, in addition to standard Gaia observations, full Sky Mapper (SM) images were recorded for ni…

Gaia Focused Product Release: Asteroid orbital solution. Properties and assessment

Gaia Collaboration, P. David, F. Mignard +2

Context. We report the exploitation of a sample of epoch astrometry for 157 000 asteroids, the same object in the Gaia Data Release 3, extended over the time coverage planned for t…

Gaia Focused Product Release: Radial velocity time series of long-period variables

Gaia Collaboration, M. Trabucchi, N. Mowlavi +403

The third Gaia Data Release (DR3) provided photometric time series of more than 2 million long-period variable (LPV) candidates. Anticipating the publication of full radial-velocit…

Colliding winds in WR21 and WR31 -- I. The X-ray view

Yael Naze, Gregor Rauw, Rachel Johnson +2

WR21 and WR31 are two WR+O binaries with short periods, quite similar to the case of V444 Cyg. The XMM-Newton observatory has monitored these two objects and clearly revealed phase…
