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…

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…
