T CrA has a companion: First direct detection of T CrA B with VLTI/MATISSE
J. Varga, A. Matter, F. Millour +21
T CrA is a Herbig Ae-type young star in a complex circumstellar environment; it includes a circumstellar disk, accretion streamers, jets, and outflows. It has long been suspected t…
The hot corino-like chemistry of four FUor-like protostars
Fernando Cruz-Sáenz de Miera, Audrey Coutens, Ágnes Kóspál +3
Context: Compared to Class 0 protostars, the higher densities and lower temperatures of the disk midplanes of Class I young stellar objects (YSOs) limit the detectability of comple…
Evidence for an accretion bridge in the DX Cha circumbinary system from VLTI/MATISSE observations
Tímea Juhász, József Varga, Péter Ábrahám +20
DX Cha (HD 104237) is a spectroscopic binary consisting of a Herbig A7.5Ve-A8Ve primary star and a K3-type companion. Here we report on new micrometer interferometric observ…
Molecular inventory of a young eruptive star's environment -- Case study of the classical FU Orionis star V1057 Cyg
Zs. M. Szabó, A. Belloche, K. M. Menten +6
Studying accretion-driven episodic outbursts in YSOs is key to understanding the later stages of star and planet formation. FU Orionis-type objects form a YSO subclass, distinguish…
Gaia20bdk -- a new FUor in Sh 2-301 Star Forming Region
M. Siwak, Á. Kóspál, P. Ábrahám +28
Context. We analyse multi-colour photometric and spectroscopic observations of a Young Stellar Object Gaia20bdk. Aims. We aim to investigate the exact nature of the eruptive phenom…
North-PHASE: Studying Periodicity, Hot Spots, Accretion Stability and Early Evolution in young stars in the northern hemisphere
A. Sicilia-Aguilar, R. S. Kahar, M. E. Pelayo-Baldárrago +17
We present the overview and first results from the North-PHASE Legacy Survey, which follows six young clusters for five years, using the 2 deg FoV of the JAST80 telescope from…
Chemical inventory of the envelope of the Class I protostar L1551 IRS 5
P. Marchand, A. Coutens, J. Scigliuto +5
Episodic accretion in protostars leads to luminosity outbursts that end up heating their surroundings. This rise in temperature pushes the snow lines back, enabling the desorption…
Discovery of a dormant 33 solar-mass black hole in pre-release Gaia astrometry
Gaia Collaboration, P. Panuzzo, T. Mazeh +412
Gravitational waves from black-hole merging events have revealed a population of extra-galactic BHs residing in short-period binaries with masses that are higher than expected base…
