The search for solar siblings has been particularly fruitful in the past few years. At present, there are four plausible candidates reported in the literature...
Searching for star-forming galaxies in the Fornax and Hydra clusters
Context. The formation and evolution of dwarf galaxies is relatively difficult to understand because of their faint emission in all regimes that require large...
Searching for the in-plane Galactic bar and ring in DENIS
New evidence for a long thin Galactic bar (in contradistinction to the bulge), as well as for the existence of the ring and the truncation of the inner disc...
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...
