ExoplaNeT accRetion mOnitoring sPectroscopic surveY (ENTROPY) III. Optical He I line profiles of the accreting super Jupiter Delorme 1 (AB)b

Gayathri Viswanath, Mickaël Bonnefoy, Catherine Dougados +8

High-resolution spectroscopic observations of helium emission lines provide a powerful probe of accretion geometry in classical T Tauri stars, revealing regions not well traced by…

Lithium and the evolution of intermediate-mass T Tauri and Herbig stars. Rotation, accretion, and planets

I. Mendigutía, J. Campbell-White, B. Montesinos +9

(Abridged) We contribute to our understanding of the evolution of young intermediate-mass stars by providing a comprehensive analysis of their lithium (Li) content. A sample of 71…

Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake. How do Planetary Systems Form?

I. Mendigutía, N. Huélamo, I. Jiménez-Serra +32

The detection and characterization of protoplanets in protoplanetary disks around young stars is emerging as a transformative field that will redefine our understanding of how plan…

ExoplaNeT accRetion mOnitoring sPectroscopic surveY (ENTROPY) - II. Time series of Balmer line profiles of Delorme 1(AB)b

Dorian Demars, Mickaël Bonnefoy, Catherine Dougados +14

Accretion processes in the planetary-mass regime remain poorly constrained, yet they strongly influence planet formation, evolution, and the composition of circumplanetary disks (C…

The Outbursting YSOs Catalogue (OYCAT)

C. Contreras Peña, J. -E. Lee, G. Herczeg +39

YSOs can display unpredictable and high-amplitude rises in brightness that can last from a few months to possibly over 100 years. These types of outbursts are explained by large ch…
