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…

Observational Chemical Signatures of the Past FU Ori Outbursts
Lis Zwicky, Tamara Molyarova, Vitaly Akimkin +4
FU Ori-type stars are young stellar objects (YSOs) experiencing luminosity outbursts by a few orders of magnitude, which last for years. A dozen of FUors are known up…

X-ray, Near-Ultraviolet, and Optical Flares Produced By Colliding Magnetospheres in The Young High-Eccentricity Binary DQ Tau
Konstantin V. Getman, Ágnes Kóspál, Nicole Arulanantham +3
DQ Tau is a unique young high-eccentricity binary system that exhibits regular magnetic reconnection flares and pulsed accretion near periastron. We conducted NuSTAR, Swift, and Ch…
