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…
A simple multipurpose double-beam optical image analyzer
Adam Popowicz, Tomasz Blachowicz
In the paper we present a low cost optical device which splits the light in the focal plane into two separate optical paths and collimates it back into a single image plane, and wh…
