Comparison of the atmosphere above the South Pole, Dome C and Dome A: first attempt
S. Hagelin, E. Masciadri, F. Lascaux +1
The atmospheric properties above three sites (Dome C, Dome A and the South Pole) on the Internal Antarctic Plateau are investigated for astronomical applications using the monthly…
Constraints on Extrasolar Planet Populations from VLT NACO/SDI and MMT SDI and Direct Adaptive Optics Imaging Surveys: Giant Planets are Rare at Large Separations
Eric L. Nielsen, Laird M. Close, Beth A. Biller +2
We examine the implications for the distribution of extrasolar planets based on the null results from two of the largest direct imaging surveys published to date. Combining the mea…
An Imaging Survey for Extrasolar Planets around 45 Close, Young Stars with SDI at the VLT and MMT
Beth A. Biller, Laird M. Close, Elena Masciadri +11
We present the results of a survey of 45 young (<250 Myr), close (<50 pc) stars with the Simultaneous Differential Imager (SDI) implemented at the VLT and the MMT for the direct de…
NACO-SDI direct imaging search for the exoplanet Eps Eri b
Markus Janson, Wolfgang Brandner, Thomas Henning +13
The active K2V star Eri hosts the most nearby known extrasolar planet. With an angular separation of about 1" on average, and an age of a few to several hundred Myrs, Eri b…
A direct and differential imaging search for sub-stellar companions to epsilon Indi A
K. Geissler, S. Kellner, W. Brandner +7
We have carried out a direct and differential imaging search for sub-stellar companions to eps Indi A using the adaptive optics system NACO at the ESO VLT. The observations were ca…
Meteorologic parameters analysis above Dome C made with ECMWF data
K. Geissler, E. Masciadri
In this paper we present the characterization of all the principal meteorological parameters (wind speed and direction, pressure, absolute and potential temperature) extended over…
