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…
X-ray Evolution of Young Stars: Early Dimming and Coronal Softening in Solar-Mass Stars with Implications for Planetary Atmospheres
Konstantin V. Getman, Eric D. Feigelson, Vladimir S. Airapetian +1
X-ray and ultraviolet (XUV) emission from young stars plays a critical role in shaping the evolution of planetary atmospheres and the conditions for habitability. To assess the lon…
Time-resolved protoplanetary disk physics in DQ Tau with JWST
Ã. Kóspál, P. Ãbrahám, V. V. Akimkin +17
Accretion variability is ubiquitous in YSOs. While large outbursts may strongly affect the disk, the effects of moderate bursts are less understood. We aim to study the physical re…
XUE. JWST spectroscopy of externally irradiated disks around young intermediate-mass stars
MarÃa Claudia RamÃrez-Tannus, Arjan Bik, Konstantin V. Getman +17
Most young stars and therefore planetary systems form in high-mass star forming regions and are exposed to ultraviolet radiation, affecting the protoplanetary disk. These regions a…
XUE 10. The CO2-rich terrestrial planet-forming region of an externally irradiated Herbig disk
Jenny Frediani, Arjan Bik, MarÃa Claudia RamÃrez-Tannus +18
We investigate the James Webb Space Telescope (JWST) MIRI MRS gas molecular content of an externally irradiated Herbig disk, the F-type XUE 10 source, in the context of the eXtreme…
XUE. Thermochemical Modeling Suggests a Compact and Gas-Depleted Structure for a Distant, Irradiated Protoplanetary Disk
Bayron Portilla-Revelo, Konstantin V. Getman, MarÃa Claudia RamÃrez-Tannus +14
Unveiling the physical structure of protoplanetary disk is crucial for interpreting the diversity of the exoplanet population. Until recently, the census of the physical properties…
