Luminous red novae (LRNe) are astrophysical transients believed to be caused by the partial ejection of a binary star's common envelope (CE) and the merger of...
Searching for the orbital period of the ultraluminous X-ray source NGC 1313 X-2
We analysed the longest phase-connected photometric data set available for NGC 1313 X-2, looking for the ˜6-day modulation reported by Liu et al.. The folded B...
Searching for the signatures of terrestrial planets in F-, G-type main-sequence stars
Context. Detailed chemical abundances of volatile and refractory elements have been discussed in the context of terrestrial-planet formation during in past...
Searching for the Signatures of Terrestrial Planets in Solar Analogs
We present a fully differential chemical abundance analysis using very high resolution (λ/δλ >~ 85, 000) and very high signal-to-noise (S/N ~800 on average)...
Searching for transiting circumbinary planets in CoRoT and ground-based data using CB-BLS
Aims: Already from the initial discoveries of extrasolar planets it was apparent that their population and environments are far more diverse than initially...
Searching for transiting cold Jupiters around bright stars with ASTEP South at Dome C, Antarctica
Much of our understanding of gas giant exoplanets come from those transiting in front of bright stars at small orbital separations (P 3 days, a 0.05 au). These...
Searching for transits in data with long time baselines and poor sampling
Aims: The standard method of searching parameter space for transits is ill-suited to data sets with long time baselines and poor temporal coverage, such as that...
Second solar spectrum of the Sr I 4607 Å line: depth probing of the turbulent magnetic field strength in a quiet region
Aims.This paper is devoted to an interpretation of Quiet-Sun, spatially-resolved spectropolarimetric observations of the Hanle effect in terms of turbulent weak...
Secondary eclipses in the CoRoT light curves. A homogeneous search based on Bayesian model selection
Aims: We aim to identify and characterize secondary eclipses in the original light curves of all published CoRoT planets using uniform detection and evaluation...
