New prospects for observing and cataloguing exoplanets in well detached binaries
R. Schwarz, B. Funk, R. Zechner +1
This paper is devoted to study the circumstances favourable to detect circumstellar and circumbinary planets in well detached binary-star-systems using eclipse timing variations (E…
Search for TeV Counterparts of Gamma-Ray Bursts with the HEGRA Experiment
H. Krawczynski, B. Funk, the HEGRA collaboration +7
The HEGRA experiment is an air shower detector system for the study of neutral and charged cosmic rays in the energy range between 500 GeV to 10 PeV. Here we give an overview of ho…
An Upper Limit on the Infrared Background Density from HEGRA data on Mkn501
B. Funk, N. Magnussen, H. Meyer +3
The energy spectrum of Mkn501 in the TeV energy regime, as measured by the HEGRA (High Energy Gamma Ray Astronomy) Cerenkov telescopes during its low state in 1995/96 and during a…
Search for gamma-ray bursts above 20 TeV with the HEGRA AIROBICC Cherenkov array
HEGRA collaboration, L. Padilla, B. Funk +34
A search for gamma-ray bursts (GRBs) above 20 TeV within the field of view (1 sr) of the HEGRA AIROBICC Cherenkov array (29N, 18W, 2200 m a.s.l.) has been performed using data take…
Prospects of the Detection of Circumbinary Planets With Kepler and CoRoT Using the Variations of Eclipse Timing
R. Schwarz, N. Haghighipour, S. Eggl +2
In close eclipsing binaries, measurements of the variations in binary's eclipse timing may be used to infer information about the existence of circumbinary objects. To determine th…
On the ultraviolet anomalies of the WASP-12 and HD 189733 systems: Trojan satellites as a plasma source
K. G. Kislyakova, E. Pilat-Lohinger, B. Funk +6
We suggest an additional possible plasma source to explain part of the phenomena observed for the transiting hot Jupiters WASP-12b and HD 189733b in their ultraviolet (UV) light cu…
A study of the stability regions in the planetary system HD 74156 - Can it host earthlike planets in habitable zones?
R. Dvorak, E. Pilat-Lohinger, B. Funk +1
Using numerical methods we thoroughly investigate the dynamical stability in the region between the two planets found in HD 74156. The two planets with minimum masses 1.56 M_JUP (H…
Eclipse timing variations to detect possible Trojan planets in binary systems
R. Schwarz, Ã. Bazsó, B. Funk +1
This paper is devoted to study the circumstances favourable to detect Trojan planets in close binary-star-systems by the help of eclipse timing variations (ETVs). To determine the…
Planets in habitable zones: A study of the binary Gamma Cephei
R. Dvorak, E. Pilat-Lohinger, B. Funk +1
The recently discovered planetary system in the binary GamCep was studied concerning its dynamical evolution. We confirm that the orbital parameters found by the observers are in a…
