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…
Frequent X-class Far UV Flares from a Young Solar Analog DS Tucanae A
Tristen Sextro, Kevin France, Vladimir Airapetian +4
The young solar analog DS Tuc A (~45 million years old, spectral type G6V) serves as an excellent proxy to the Sun during early stages of the Earth's evolution. The young Sun's enh…
Magnetic Heating Across the Sun and Solar-like Stars: Universal Scaling Laws from Chromospheres to Coronae
Shin Toriumi, Kosuke Namekata, Yuta Notsu +2
Magnetic activity in cool stars governs the thermal structure and high-energy radiative output of their outer atmospheres, thereby influencing stellar evolution, stellar winds, and…
Exploring Activity Across the Stellar Main Sequence with the Sun as a Benchmark
Atul Mohan, Stephen M. White, Sven Wedemeyer +1
The active atmospheres of cool main-sequence stars (F-M type) often release a fraction of their stored magnetic energy, producing enhanced emissions (flares) across radio to X-ray…
The role of the Hubble Space Telescope in advancing our understanding of atmospheric escape in exoplanets
Leonardo A. Dos Santos, Arika Egan, Kevin France +14
An important evolutionary pathway for planetary atmospheres is escape to space, which has been studied on Earth and Mars for several decades and more recently in exoplanets. A part…
Exploring Space Weather From Young Solar-like Stars as Windows to Exoplanetary Habitability
V. S. Airapetian, K. Namekata, K. France +10
Young solar-like stars are efficient generators of magnetic activity, superflares, coronal mass ejections (CMEs), and stellar energetic particles. These phenomena drive the early e…
Multiwavelength Campaign Observations of a Young Solar-type Star, EK Draconis. III. Comparison between Starspot Mapping, Zeeman Doppler Imaging, and Multiwavelength Variability
Kai Ikuta, Kosuke Namekata, Pascal Petit +12
Recent simultaneous multiwavelength observations of a nearby young solar-type star EK Dra in the optical, H spectrum, and X-ray, have provided evidence for stellar prominence er…
