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…
Multi-Observatory Study of Young Stellar Energetic Flares (MORYSEF): No Evidence For Abnormally Strong Stellar Magnetic Fields After Powerful X-ray Flares
Konstantin V. Getman, Oleg Kochukhov, Joe P. Ninan +9
We explore the empirical power-law relationship between X-ray luminosity (Lx) and total surface magnetic flux (Phi), established across solar magnetic elements, time- and disk-aver…
Multi-Observatory Research of Young Stellar Energetic Flares (MORYSEF): X-ray Flare Related Phenomena and Multi-epoch Behavior
Konstantin V. Getman, Eric D. Feigelson, Abygail R. Waggoner +8
The most powerful stellar flares driven by magnetic energy occur during the early pre-main sequence (PMS) phase. The Orion Nebula represents the nearest region populated by young s…
Classification of X-ray Flare Driven Chemical Variability in Protoplanetary Disks
Abygail R. Waggoner, L. Ilsedore Cleeves
Young stars are highly variable in the X-ray regime. In particular, bright X-ray flares can substantially enhance ionization in the surrounding protoplanetary disk. Since disk chem…
Modeling Time Dependent Water Chemistry Due to Powerful X-ray Flares from T-Tauri Stars
Abygail R. Waggoner, L. Ilsedore Cleeves
Young stars emit strong flares of X-ray radiation that penetrate the surface layers of their associated protoplanetary disks. It is still an open question as to whether flares crea…
