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…

Glancing through the debris disk: Photometric analysis of DE Boo with CHEOPS

Á. Boldog, Gy. M. Szabó, L. Kriskovics +76

DE Boo is a unique system, with an edge-on view through the debris disk around the star. The disk, which is analogous to the Kuiper belt in the Solar System, was reported to extend…

Fraction of Stars in Clusters for the LEGUS Dwarf Galaxies

D. O. Cook, J. C. Lee, A. Adamo +20

We study the young star cluster populations in 23 dwarf and irregular galaxies observed by the HST Legacy ExtraGalactic Ultraviolet Survey (LEGUS), and examine relationships betwee…

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 all-sky PLATO input catalogue

M. Montalto, G. Piotto, P. M. Marrese +29

Context. The ESA PLAnetary Transits and Oscillations of stars (PLATO) mission will search for terrestrial planets in the habitable zone of solar-type stars. Because of telemetry li…

Estimating Magnetic Filling Factors From Simultaneous Spectroscopy and Photometry: Disentangling Spots, Plage, and Network

T. W. Milbourne, D. F. Phillips, N. Langellier +21

State of the art radial velocity (RV) exoplanet searches are limited by the effects of stellar magnetic activity. Magnetically active spots, plage, and network regions each have di…
