New Radial Velocities for 30 Candidate Runaway Stars and a Possible Binary Supernova Origin for HIP 9470 and PSR J0152-1637
N. Tetzlaff, G. Torres, A. Bieryla +1
We report new radial velocity measurements for 30 candidate runaway stars. We revise their age estimates and compute their past trajectories in the Galaxy in order to determine the…
Transit timing of TrES-2: a combined analysis of ground- and space-based photometry
St. Raetz, G. Maciejewski, Ch. Ginski +21
Homogeneous observations and careful analysis of transit light curves can lead to the identification of transit timing variations (TTVs). TrES-2 is one of few exoplanets, which off…
On identifying the neutron star that was born in the supernova that placed 60Fe onto the Earth
R. Neuhäuser, N. Tetzlaff, T. Eisenbeiss +1
Recently, 60Fe was found in the Earth crust formed in a nearby recent supernova (SN). If the distance to the SN and mass of the progenitor of that SN was known, then one could cons…
Constraints on neutron-star theories from nearby neutron star observations
Ralph Neuhäuser, Valeri V. Hambaryan, Nina Tetzlaff +2
We try to constrain the nuclear Equation-of-State (EoS) and supernova ejecta models by observations of young neutron stars in our galactic neighbourhood. There are seven thermally…
A new flare star member candidate in the Pleiades cluster
M. Moualla, T. O. B. Schmidt, R. Neuhäuser +19
We present a new flare star, which was discovered during our survey on a selected field at the edge of the Pleiades cluster. The field was observed in the period 2007 - 2010 with t…
Young Exoplanet Transit Initiative (YETI)
R. Neuhäuser, R. Errmann, A. Berndt +80
We present the Young Exoplanet Transit Initiative (YETI), in which we use several 0.2 to 2.6m telescopes around the world to monitor continuously young (< 100 Myr), nearby (< 1 kpc…
