Direct Imaging discovery of a second planet candidate around the possibly transiting planet host CVSO 30
T. O. B. Schmidt, R. Neuhäuser, C. Briceño +11
We surveyed the 25 Ori association for direct-imaging companions. This association has an age of only few million years. Among other targets, we observed CVSO 30, which has recentl…
First spectroscopic observations of the sub-stellar companion of the young debris disk star PZ Telescopii
T. O. B. Schmidt, M. Mugrauer, R. Neuhäuser +5
In 2010 a sub-stellar companion to the solar analog pre-main sequence star PZ Tel and member of the about 12 Myr old Beta Pic moving group was found by high-contrast direct imaging…
Ionisation in atmospheres of Brown Dwarfs and extrasolar planets I The role of electron avalanche
Ch. Helling, M. Jardine, S. Witte +1
Brown Dwarf and extrasolar planet atmospheres form clouds which strongly influence the local chemistry and physics. These clouds are globally neutral obeying dust-gas charge equili…
Direct evidence of a sub-stellar companion around CT Cha
T. O. B. Schmidt, R. Neuhäuser, A. Seifahrt +5
In our ongoing search for close and faint companions around T Tauri stars, we found a very faint (Ks=14.9mag, Ks_0=14.4mag) object, just ~2.67" northwest of the Chamaeleon star-for…
