A multiwavelength radial velocity search for planets around the brown dwarf LP 944-20
E. L. Martin, E. Guenther, M. R. Zapatero Osorio +2
The nearby brown dwarf LP 944-20 has been monitored for radial velocity variability at optical and near-infrared wavelengths using the VLT/UVES and the Keck/NIRSPEC spectrographs,…
A young binary Brown Dwarf in the R-CrA star formation region
H. Bouy, W. Brandner, E. L. Martin +5
We present imaging and spectroscopic observations with HST (WFPC2, ACS/HRC and STIS), VLT (FORS2) and Keck (HIRES) of the dM8 ultra-cool dwarf DENIS-P J185950.9-370632, located in…
Spiral shocks in the accretion disc of IP Peg during outburst maximum
E. T. Harlaftis, D. Steeghs, K. Horne +2
In response to our recent discovery of spiral arms in the accretion disc of IP Peg during rise to outburst, we have obtained time-resolved spectrophotometry of IP Peg during outbur…
Search for young low-mass stars in a ROSAT selected sample south of the Taurus-Auriga molecular clouds
A. Magazzu, E. L. Martin, M. F. Sterzik +3
We present results of intermediate resolution spectroscopy of 131 optical counterparts to 115 ROSAT All-Sky Survey X-ray sources south of the Taurus-Auriga dark cloud complex. Thes…
