Blue large-amplitude pulsators as a new class of variable stars
Sign Up to like & getrecommendations! Published in 2017 at "Nature Astronomy"
DOI: 10.1038/s41550-017-0166
Abstract: A previously unidentified class of variable stars has been found in OGLE survey data, characterized by periodic brightness variations on ~30-min timescales, amplitudes of ~0.3 mag and temperatures of ~30,000 K. They are potentially evolved low-mass stars. read more here.

DOI: 10.1088/1538-3873/ac4398
Abstract: Proper photometric data are challenging to obtain in the K2 mission of the Kepler space telescope due to strong systematics caused by the two-wheel-mode operation. It is especially true for variable stars wherein physical phenomena… read more here.
