The luminosity of the bulge was an important parameter in the early classification of galaxies. Later a large dispersion was found between the bulge-to-total (B...
Background solar irradiance spectrum at high and low phases of the solar activity cycle
Two data series of disk integrated solar irradiance, taken by the Variability of the solar IRradiance and Gravity Oscillations (VIRGO) experiment on board the...
Background solar velocity spectrum at high and low phases of solar activity cycle
Using GOLF/SOHO data a detailed analysis of the solar background spectrum has been performed at high and low phases of solar activity cycle. The analysis...
Balloon 090100001: a Link Between the Two Classes of Pulsating Hot Subdwarfs
We present results of photometric observations of the high-amplitude EC 14026-type star, Balloon 090100001. The data were obtained in broad-band B filter and...
Balloon 090100001 is the brightest (B=11.8) pulsator sdB of the EC14026 class. Moreover, it shows a frequency mode (at 356 s, 2.81 mHz) with one of the hightest...
Balmer-dominated shocks in Tycho's SNR: omnipresence of CRs
We present wide-field, spatially and highly resolved spectroscopic observations of Balmer filaments in the northeastern rim of Tycho's supernova remnant in...
BaLROG: The Influence of Bars on the Dynamical Structure in Nearby Galaxies
Using the BaLROG (Bars in Low Redshift Optical Galaxies) sample of 16 morphologically distinct barred spirals, we constrain the influence of bars on nearby...
