XUE. ProDiMo models of internally and externally irradiated planet-forming disks around 0.3-4.0 solar mass stars (The IRIS project I)

Jenny Frediani, Konstantin V. Getman, Peter Woitke +18

Most stars and planets form in massive star-forming regions, where disks are exposed to external far-ultraviolet (FUV) radiation from nearby O- and B-type stars. The combined effec…

The Effect of X-Ray and Accretion Variability on Mid-Infrared Lines in the Young Disk-Bearing Binary DQ Tau

Bayron Portilla-Revelo, Konstantin V. Getman, Ágnes Kóspál +5

A star's radiation field is the main energy source of a planet-forming disk. Stellar photons---from X-rays to optical---are reprocessed in the inner protoplanetary disk enabling mi…

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

Á. Kóspál, P. Ábrahám, 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 10. The CO2-rich terrestrial planet-forming region of an externally irradiated Herbig disk

Jenny Frediani, Arjan Bik, María Claudia Ramírez-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…
