JWST/MIRI Spectroscopy of the Disk of the Young Eruptive Star EX Lup in Quiescence
Ágnes Kóspál, Péter Ábrahám, Lindsey Diehl +7
EX Lup is a low-mass pre-main sequence star that occasionally shows accretion-related outbursts. Here, we present JWST/MIRI medium resolution spectroscopy obtained for EX Lup fourt…
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…
A likely flyby of binary protostar Z CMa caught in action
Ruobing Dong, Hauyu Baobab Liu, Nicolas Cuello +16
Close encounters between young stellar objects in star forming clusters are expected to dramatically perturb circumstellar disks. Such events are witnessed in numerical simulations…
A mid-infrared interferometric survey of the planet-forming region around young Sun-like stars
J. Varga, P. Ábrahám, L. Chen +3
We present our results from a mid-infrared interferometric survey targeted at the planet-forming region in the circumstellar disks around low- and intermediate-mass young stars. Ou…
Variable warm dust around the Herbig Ae star HD~169142: Birth of a ring?
Lei Chen, Attila Moor, Alexander Kreplin +7
The Herbig Ae star HD 169142 is known to have a gaseous disk with a large inner hole, and also a photometrically variable inner dust component in the sub-au region. Following up ou…
An ALMA Study of the FU-Ori Type Object V900 Mon: Implications for the Progenitor
Michihiro Takami, Tsu-Sheng Chen, Hauyu Baobab Liu +13
We present ALMA observations of 12CO, 13CO, and C18O J=2--1 lines and the 230 GHz continuum for the FU Ori-type object (FUor) V900 Mon (d~1.5 kpc), for which the accretion burst wa…
Near-infrared interferometric observation of the Herbig Ae star HD144432 with VLTI/AMBER
Lei Chen, Alexander Kreplin, Yang Wang +9
We study the sub-AU-scale circumstellar environment of the Herbig Ae star HD144432 with near-infrared (NIR) VLTI/AMBER observations to investigate the structure of its inner dust d…
Reprocessed emission from warped accretion discs induced by the Bardeen-Petterson effect
Sheng-Miao Wu, Lei Chen, Feng Yuan
The broad Balmer emission-line profiles resulting from the reprocessing of UV/X-ray radiation from a warped accretion disc induced by the Bardeen-Petterson effect are studied. We a…
Steady state solution of warped accretion discs
Lei Chen, Shengmiao Wu, Feng Yuan
We consider a thin accretion disc warped due to the Bardeen-Petterson effect, presenting both analytical and numerical solutions for the situation that the two viscosity coefficien…
