Tracing Accretion and Inner-Disk Gas Evolution in the Orion Nebula via Br-alpha and CO
Konstantin V. Getman, Maria Claudia Ramirez-Tannus, Jenny Frediani +17
We present a systematic spectroscopic study of hydrogen Brackett-alpha (Br-alpha) and carbon monoxide (CO) fundamental-band (4.3-5.2 micron) emission from a homogeneous sample of 0…
Chandra-JWST Probing the Effects of Moderate X-Ray Superflares on Protoplanetary Disks
Konstantin V. Getman, Kevin L. Luhman, Bayron Portilla-Revelo +17
Powerful X-ray flares from young stars may rapidly alter the physical and chemical conditions of their planet-forming disks, but direct observational tests remain scarce. We presen…
The past, present and future of observations of externally irradiated disks
Planet formation environments collaboration, Megan Allen, Rossella Anania +51
Recent years have seen a surge of interest in the community studying the effect of ultraviolet radiation environment, predominantly set by OB stars, on protoplanetary disc evolutio…
XUE. Molecular inventory in the inner region of an extremely irradiated Protoplanetary Disk
María Claudia Ramirez-Tannus, Arjan Bik, Lars Cuijpers +24
We present the first results of the eXtreme UV Environments (XUE) James Webb Space Telescope (JWST) program, that focuses on the characterization of planet forming disks in massive…
The GRAVITY young stellar object survey. II. First spatially resolved observations of the CO bandhead emission in a high-mass YSO
GRAVITY Collaboration, A. Caratti o Garatti, R. Fedriani +50
The inner regions of the discs of high-mass young stellar objects (HMYSOs) are still poorly known due to the small angular scales and the high visual extinction involved. We deploy…
The young stellar content of the giant HII regions M8, G333.6-0.2, and NGC6357 with VLT/KMOS
M. C. Ramírez-Tannus, J. Poorta, A. Bik +14
Context: The identification and characterisation of populations of young massive stars in (giant) HII regions provides important constraints on i) the formation process of massive…
