According to theory, high energy emission from the coronae of cool stars can severely erode the atmosphere of orbiting planets. To test the long term effects of...
Planets of young stars: the TLS radial velocity survey
We report on the search for planets orbiting 46 nearby young stars performed at the State Observatory of Turingia (TLS) by means of a radial velocity survey...
Plenoptic wavefront sensor for free-space optical communications
A plenoptic wavefront sensor is proposed for the measurement of the atmospheric turbulence on satellite-toground optical communications. The design will be...
