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…
Effects of energetic particles produced by magnetic reconnection on discs of young stars
Valentin Brunn
T Tauri stars and their discs are crucial for understanding stellar evolution and the formation of planets in low-mass systems. These stars exhibit significant variability, notably…
The role of heating on the formation and the dynamics of YSO jets : I. A parametric study
C. Meskini, C. Sauty, A. Marcowith +2
Theoretical arguments as well as observations of young stellar objects (YSO) support the presence of a diversified circumstellar environment. A stellar jet is thought to account fo…
