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…
Machine learning-accelerated chemistry modeling of protoplanetary disks
Grigorii V. Smirnov-Pinchukov, Tamara Molyarova, Dmitry A. Semenov +4
Aims. With the large amount of molecular emission data from (sub)millimeter observatories and incoming James Webb Space Telescope infrared spectroscopy, access to fast forward mode…
The Young Binary DQ Tau Produces Another X-ray Flare Near Periastron
Konstantin V. Getman, Vitaly V. Akimkin, Nicole Arulanantham +4
This work is part of a multi-wavelength program to study the effects of X-ray/UV/optical stellar radiation on the chemistry of the circumbinary disk around the young high-eccentric…
Lack of other molecules in CO-rich debris discs: is it primordial or secondary gas?
Grigorii V. Smirnov-Pinchukov, Attila Moór, Dmitry A. Semenov +5
The nature of the gas in CO-rich debris discs remains poorly understood, as it could either be a remnant from the earlier Class II phase or of secondary origin, driven by the destr…
Using HCO isotopologues as tracers of gas depletion in protoplanetary disk gaps
Grigorii V. Smirnov-Pinchukov, Dmitry A. Semenov, Vitaly V. Akimkin +1
The widespread rings and gaps seen in the dust continuum in protoplanetary disks are sometimes accompanied by similar substructures seen in molecular line emission. One example is…
