Exocomets: A spectroscopic survey
(European Southern Observatory, 2020)
Context. While exoplanets are now routinely detected, the detection of small bodies in extrasolar systems remains challenging. Since the discovery of sporadic events interpreted as exocomets (Falling Evaporating Bodies) ...
Properties of RR Lyrae stars in the inner regions of the Large Magellanic Cloud. III. Near-infrared study
(2009)
Context: RR Lyrae variable stars are the primary Population II distance indicator. Likewise, the Large Magellanic Cloud (LMC) constitutes a key step in the extragalactic distance scale. Aims: By combining near-IR photometry ...
A lack of close binaries among hot horizontal branch stars in globular clusters. II. NGC 2808
(2011)
Context. The formation mechanism of hot horizontal branch (HB) stars is still one of the most uncertain points of stellar evolution theories. In the past decade, models based on their binary origin have been very successful ...
