Ultraviolet Imaging of SR 12 c with HST/WFC3: Accretion and Variability of a Giant Planet at the End Stages of Growth
Claire O. Finley, Brendan P. Bowler, Ya-Lin Wu +12
Many details of the gas accretion phase during giant planet formation remain untested. We present new 0.2$\unicode{x2013}$0.7 m UV-through-red optical imaging of the young, wid…
PENELLOPE: IX. Lithium, iron and barium elemental abundances in eight nearby young clusters
R. Carini, K. Biazzo, A. Frasca +19
We conducted a homogeneous chemical analysis of pre-main sequence stars with effective temperatures ranging from 3000 K to 5500 K in eight nearby star-forming regions…
JWST-TST High Contrast: Medium-resolution spectroscopy reveals a carbon-rich circumplanetary disk around the young accreting exoplanet Delorme 1 AB b
Mathilde Mâlin, Kimberly Ward-Duong, Sierra L. Grant +21
Young accreting planetary-mass objects are thought to draw material from a circumplanetary disk (CPD) composed of gas and dust. While the gas within the disk is expected to dispers…
The ODYSSEUS Survey. Using accretion and stellar rotation to reveal the star-disk connection in T Tauri stars
Caeley V. Pittman, C. C. Espaillat, Zhaohuan Zhu +4
Classical T Tauri stars (CTTS) exhibit strong variability over timescales of minutes to decades. However, much theoretical work assumes that CTTS are in stable spin states. Here, w…
The ODYSSEUS Survey. Characterizing magnetospheric geometries and hotspot structures in T Tauri stars
Caeley V. Pittman, C. C. Espaillat, Connor E. Robinson +20
Magnetospheric accretion is a key process that shapes the inner disks of T Tauri stars, controlling mass and angular momentum evolution. It produces strong ultraviolet and optical…
