Ground-based exoplanet near-infrared search by imaging and spectroscopy: 3 new companion candidates in TWA
Ralph Neuhaeuser, Nuria Huelamo, Eike W. Guenther +5
We report first results from our ground-based infrared imaging search for sub-stellar companions (brown dwarfs and giant planets) of young (up to 100 Myrs) nearby (up to 100 pc) st…
Identification of the donor in GRS 1915+105
J. Greiner, M. J. McCaughrean, J. G. Cuby +2
We report on the results of medium-resolution spectroscopy of GRS 1915+105 in the H and K band using the 8m VLT at ESO. We clearly identify absorption bandheads from CO12 and CO13.…
Halpha emitting galaxies and the cosmic star formation rate at z = 2.2
Alan F. M. Moorwood, Paul P. van der Werf, Jean Gabriel Cuby +1
About 10 candidate Halpha emitting galaxies at z = 2.2 have been detected in a 2.1 um narrow band imaging survey covering an area of 100 sq. arcmin including the WFPC2 and STIS fie…
Direct imaging search for planetary companions next to young nearby stars
R. Neuhaeuser, E. Guenther, W. Brandner +6
We report first results from our ground-based infrared imaging search for sub-stellar companions (brown dwarfs and giant planets) of young (up to 100 Myrs) nearby (up to 75 pc) sta…
Discovery of a faint Field Methane Brown Dwarf from ES0 NTT and VLT observations
J. G. Cuby, P. Saracco, A. F. M. Moorwood +4
We report the discovery of an isolated brown dwarf with similar properties to the binary object Gliese 229B and to the newly discovered field brown dwarf SDSS 1624+00. Although exh…
