Monte-Carlo radiative transfer simulation of the circumstellar disk of the Herbig Ae star HD 144432
L. Chen, A. Kreplin, G. Weigelt +6
Studies of pre-transitional disks, with a gap region between the inner infrared-emitting region and the outer disk, are important to improving our understanding of disk evolution a…
VLTI-MATISSE L- and N-band aperture-synthesis imaging of the unclassified B[e] star FS Canis Majoris
K. -H. Hofmann, A. Bensberg, D. Schertl +58
Context: FS Canis Majoris (FS CMa, HD 45677) is an unclassified B[e] star surrounded by an inclined dust disk. The evolutionary stage of FS CMa is still debated. Perpendicular to t…
Revealing the inner circumstellar disk of the T Tauri star S CrA N using the VLTI
J. Vural, A. Kreplin, S. Kraus +7
Aims: We investigate the structure of the circumstellar disk of the T Tauri star S CrA N and test whether the observations agree with the standard picture proposed for Herbig Ae st…
Tracing jet emission at the base of a high-mass YSO. First AMBER/VLTI observations of the Brγemission in IRAS 13481-6124
A. Caratti o Garatti, B. Stecklum, G. Weigelt +9
To probe the circumstellar environment of IRAS 13481-6124, a 20 M_sun high-mass young stellar object (HMYSO) with a parsec-scale jet and accretion disc, we investigate the origin o…
On the ALMA observability of nascent massive multiple systems formed by gravitational instability
D. M. -A. Meyer, A. Kreplin, S. Kraus +3
Massive young stellar object (MYSOs) form during the collapse of high-mass pre-stellar cores, where infalling molecular material is accreted through a centrifugally-balanced accret…
AMBER/VLTI observations of the B[e] star MWC 300
Y. Wang, G. Weigelt, A. Kreplin +8
Aims. We study the enigmatic B[e] star MWC 300 to investigate its disk and binary with milli-arcsecond-scale angular resolution. Methods. We observed MWC 300 with the VLTI/AMBER in…
