New Arabic records from Cairo on supernovae 1181 and 1006
J. G. Fischer, H. Halm, R. Neuhäuser +1
The remnant of the historical supernova SN 1181 is under discussion: While the previously suggested G130.7+3.1 (3C58) appears too old (3000-5000 yr), the unusual star IRAS 00500+67…
Transit Timing Analysis in the HAT-P-32 system
M. Seeliger, D. Dimitrov, D. Kjurkchieva +24
We present the results of 45 transit observations obtained for the transiting exoplanet HAT-P-32b. The transits have been observed using several telescopes mainly throughout the YE…
Revisiting parameters for the WASP-1 planetary system
G. Maciejewski, J. Ohlert, D. Dimitrov +8
We present thirteen new transit light curves for the WASP-1 b exoplanet. Observations were acquired with 0.5 - 1.2-m telescopes between 2007 and 2013. Our homogeneous analysis, whi…
Radial-velocity survey of members and candidate members of the TW Hydrae association
Guillermo Torres, Eike W. Guenther, Laurence A. Marschall +3
We report our spectroscopic observations of stars belonging to the young nearby group known as the TW Hydrae association, as well as of a number of potential members of the associa…
Multiplicity, kinematics and rotation rates of very young brown dwarfs in ChaI
Viki Joergens, Ralph Neuhäuser, Eike W. Guenther +2
We have studied twelve very young (1-5Myr) bona fide and candidate brown dwarfs in the ChaI star forming region in terms of their kinematic properties, the occurrence of multiple s…
