The VISCACHA survey -- IV. The SMC West Halo in 8D
B. Dias, M. C. Parisi, M. Angelo +18
The structure of the Small Magellanic Cloud (SMC) is very complex, in particular in the periphery that suffers more from the interactions with the Large Magellanic Cloud (LMC). A w…
Discovery of 74 new bright ZZ Ceti stars in the first three years of TESS
A. D. Romero, S. O. Kepler, J. J. Hermes +17
We report the discovery of 74 new pulsating DA white dwarf stars, or ZZ Cetis, from the data obtained by the Transiting Exoplanet Survey Satellite (TESS) mission, from Sectors 1 to…
VVV-WIT-08: the giant star that blinked
Leigh C. Smith, Sergey E. Koposov, Philip W. Lucas +11
We report the serendipitous discovery of a late-type giant star that exhibited a smooth, eclipse-like drop in flux to a depth of 97 per cent. Minimum flux occurred in April 2012 an…
Spectroscopic study of the HII regions in the NGC 1232 galaxy
Fabiana Lima-Costa, Lucimara P. Martins, Alberto Rodríguez-Ardila +1
NGC 1232 is a face-on spiral galaxy that serves as an excellent laboratory for the study of star formation due to its proximity. Recent studies have revealed interesting features a…
The VISCACHA survey -- II. Structure of star clusters in the Magellanic Clouds periphery
J. F. C. Santos, F. F. S. Maia, B. Dias +11
We provide a homogeneous set of structural parameters of 83 star clusters located at the periphery of the Small Magellanic Cloud (SMC) and the Large Magellanic Cloud (LMC). The clu…
Rotational modulation and single g-mode pulsation in the B9pSi star HD174356?
Z. Mikulasek, E. Paunzen, S. Huemmerich +19
Chemically peculiar (CP) stars of the upper main sequence are characterised by specific anomalies in the photospheric abundances of some chemical elements. The group of CP2 stars,…
