First evidence for a spatially resolved disk structure around the Herbig Ae star R CrA
S. Correia, R. Koehler, G. Meeus +1
We present mid-infrared interferometric observations of the Herbig Ae star R CrA obtained with MIDI at the VLTI using several projected baselines in the UT2-UT3 configuration. The…
Spectroscopic classification of red high proper motion objects in the Southern Sky
N. Lodieu, R. -D. Scholz, M. J. McCaughrean +3
We present the results of spectroscopic follow-up observations for a sample of 71 red objects with high proper motions in the range 0.08-1.14 arcsec/yr as detected using APM and SS…
The nearest cool white dwarf (d~4pc), the coolest M-type subdwarf (sdM9.5), and other high proper motion discoveries
R. -D. Scholz, I. Lehmann, I. Matute +1
We report the discovery of seven high proper motion stars with proper motions between about 0.7 and 2.2 arcsec/yr. They were detected in an archival search using multi-epoch positi…
Observations and Theory of Star Cluster Formation
B. G. Elmegreen, Y. N. Efremov, R. E. Pudritz +1
Young stars form on a wide range of scales, producing aggregates and clusters with various degrees of gravitational self-binding. The loose aggregates have a hierarchical structure…
UV to X-ray Spectra of Radio-Quiet Quasars. Comparison With Accretion Disk Models
H. Brunner, C. Mueller, P. Friedrich +3
We present UV to soft X-ray spectra of 31 radio-quiet quasars, comprising data from the IUE ULDA database and the ROSAT pointed observation phase. 90 % of the sample members show a…
