The BRITE-Constellation Nanosatellite Space Mission And Its First Scientific Results
G. Handler, A. Pigulski, W. W. Weiss +15
The BRIght Target Explorer (BRITE) Constellation is the first nanosatellite mission applied to astrophysical research. Five satellites in low-Earth orbits perform precise optical t…
Pulsations and outbursts in Be stars: Small differences - big impacts
D. Baade, Th. Rivinius, A. Pigulski +12
New high-cadence observations with BRITE covering many months confirm that coupled pairs of nonradial pulsation modes are widespread among early-type Be stars. With the difference…
Combining BRITE and ground-based photometry for the Beta Cephei star Nu Eridani: impact on photometric pulsation mode identification and detection of several g modes
G. Handler, M. Rybicka, A. Popowicz +12
We report a simultaneous ground and space-based photometric study of the Beta Cephei star Nu Eridani. Half a year of observations have been obtained by four of the five satellites…
A method of complex background estimation in astronomical images
Adam Popowicz, Bogdan Smolka
In this paper, we present a novel approach to the estimation of strongly varying backgrounds in astronomical images by means of small objects removal and subsequent missing pixels…
On the efficiency of techniques for the reduction of impulsive noise in astronomical images
A. Popowicz, A. R. Kurek, T. Blachowicz +2
The impulsive noise in astronomical images originates from various sources. It develops as a result of thermal generation in pixels, collision of cosmic rays with image sensor or m…
The BRITE Constellation nanosatellite mission: Testing, commissioning and operations
H. Pablo, G. N. Whittaker, A. Popowicz +27
BRITE (BRIght Target Explorer) Constellation, the first nanosatellite mission applied to astrophysical research, is a collaboration among Austria, Canada and Poland. The fleet of s…
