Gaia21bty: An EXor lightcurve exhibiting an FUor spectrum

Michał Siwak, Lynne A. Hillenbrand, Ágnes Kóspál +16

Gaia21bty, a pre-main sequence star that previously had shown aperiodic dips in its light curve, underwent a considerable mag brightening that occurred over a few mo…

Primordial or Secondary? Testing models of debris disk gas with ALMA

Gianni Cataldi, Yuri Aikawa, Kazunari Iwasaki +13

The origin and evolution of gas in debris disks is still not well understood. Secondary gas production from cometary material or a primordial origin have been proposed. So far, obs…

The Detection of a Compact Radio Feature in a Seyfert Galaxy After an Accretion Rate Change

K. É. Gabányi, K. Smith, S. Frey +3

X-ray binaries are known to show state transitions related to accretion rate changes which are often accompanied with dramatic changes in the jet emission. However, it is not clear…

Mid-infrared time-domain study of recent dust production events in the extreme debris disc of TYC 4209-1322-1

A. Moór, P. Ábrahám, Á. Kóspál +23

Extreme debris discs are characterized by unusually strong mid-infrared excess emission, which often proves to be variable. The warm dust in these discs is of transient nature and…

A gap at 1 au in the disk of DI Cha A revealed by infrared interferometry

Tímea Juhász, Péter Ábrahám, Attila Moór +6

DI Cha A is K0-type pre-main sequence star, the brightest component of a quadruple stellar system. Here we report on a detailed study of this star based on archival VLTI/MIDI and V…

Multiwavelength Vertical Structure in the AU Mic Debris Disk: Characterizing the Collisional Cascade

David Vizgan, A. Meredith Hughes, Evan S. Carter +9

Debris disks are scaled-up analogs of the Kuiper Belt in which dust is generated by collisions between planetesimals. In the "collisional cascade" model of debris disks, dust lost…
