Euclid Quick Data Release (Q1). Quenching precedes bulge formation in dense environments but follows it in the field

Euclid Collaboration, F. Gentile, E. Daddi +321

(Abridged) The bimodality between star-forming discs and quiescent spheroids requires the existence of two main processes: the galaxy quenching and the morphological transformation…

Blind search for activity-sensitive lines in the near-infrared using HARPS and NIRPS observations of Proxima and Gl 581

João Gomes da Silva, Elisa Delgado-Mena, Nuno C. Santos +145

Stellar activity variability is one of the main obstacles to the detection of Earth-like planets using the RV method. The aim of this work is to measure the effect of activity in t…

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…

The Growth of Intracluster Light in XCS-HSC Galaxy Clusters from

Kate E. Furnell, Chris A. Collins, Lee S. Kelvin +14

We estimate the Intracluster Light (ICL) component within a sample of 18 clusters detected in XMM Cluster Survey (XCS) data using deep ( 26.8 mag) Hyper Suprime Cam Subaru St…

Stellar chromospheric activity of 1,674 FGK stars from the AMBRE-HARPS sample I. A catalogue of homogeneous chromospheric activity

J. Gomes da Silva, N. C. Santos, V. Adibekyan +9

We present a catalogue of homogeneous determined chromospheric emission (CE), stellar atmospheric parameters and ages for 1,674 FGK main sequence (MS), subgiant, and giant stars. T…

On using dipolar modes to constrain the helium glitch in red-giant stars

G. Dréau, M. S. Cunha, M. Vrard +1

The space-borne missions CoRoT and Kepler have revealed numerous mixed modes in red-giant stars. These modes carry a wealth of information about red-giant cores, but are of limited…
