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: 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…

Strong Carbon Features and a Red Early Color in the Underluminous Type Ia SN 2022xkq

Jeniveve Pearson, David J. Sand, Peter Lundqvist +85

We present optical, infrared, ultraviolet, and radio observations of SN 2022xkq, an underluminous fast-declining type Ia supernova (SN Ia) in NGC 1784 ( Mpc),…

The Pristine survey -- XXIII. Data Release 1 and an all-sky metallicity catalogue based on Gaia DR3 BP/RP spectro-photometry

Nicolas F. Martin, Else Starkenburg, Zhen Yuan +38

We used the spectro-photometric information of ~219 million stars from Gaia's DR3 to calculate synthetic, narrow-band, metallicity-sensitive CaHK magnitudes that mimic the observat…

GTC Follow-up Observations of Very Metal-Poor Star Candidates from DESI

Carlos Allende Prieto, David S. Aguado, Jonay I. González Hernández +48

The observations from the Dark Energy Spectroscopic Instrument (DESI) will significantly increase the numbers of known extremely metal-poor stars by a factor of ~ 10, improving the…

Detection of barium in the atmospheres of the ultra-hot gas giants WASP-76b and WASP-121b

T. Azevedo Silva, O. D. S. Demangeon, N. C. Santos +33

High-resolution spectroscopy studies of ultra-hot Jupiters have been key in our understanding of exoplanet atmospheres. Observing into the atmospheres of these giant planets allows…

Revisiting Proxima with ESPRESSO

A. Suárez Mascareño, J. P. Faria, P. Figueira +88

We aim to confirm the presence of Proxima b using independent measurements obtained with the new ESPRESSO spectrograph, and refine the planetary parameters taking advantage of its…
