Abstract:
The BRIght Target Explorer (BRITE) mission collects photometric time
series in two passbands with the aim of investigating stellar
structure and evolution. Since their launches in the years 2013 and
2014, the constellation of five BRITE nano-satellites has observed a
total of more than 700 individual bright stars in 64 fields. Some
targets have been observed multiple times. Thus, the total time base
of the datasets acquired for those stars can be as long as nine years.
Our aim is to provide a complete description of ready-to-use BRITE
data, to show the scientific potential of the BRITE-Constellation data
by identifying the most interesting targets, and to demonstrate how
scientists can use these data in their research, and encourage them to
do so.
We applied a decorrelation process to the automatically reduced
BRITE-Constellation data to correct for instrumental effects. We
performed a statistical analysis of the light curves obtained for the
300 stars observed in the first 14 fields during the first ∼2.5 yr of
the mission. We also performed cross-identification with the
International Variable Star Index.
We present the data obtained by the BRITE-Constellation mission in the
first 14 fields it observed, from November 2013 to April 2016. We also
describe the properties of the data for these fields and the 300 stars
observed in them. Using these data, we detect variability in 64% of
the presented sample of stars. Sixty-four stars, or 21.3% of the
sample, have not yet been identified as variable in the literature and
their data have not been analysed in detail. They can therefore
provide valuable scientific material for further research. All data
are made publicly available through the BRITE Public Data Archive and
the Canadian Astronomy Data Centre.
Description:
Data obtained in the first 14 fields between November 2013 and April
2016 by the five operational BRITE nano-satellites. The V magnitudes
of the 300 stars in this sample range from -0.72 to 6.91, showing that
the BRITE satellites were able to obtain photometry for stars much
fainter than the originally assumed limit of V=4.0mag.
