Surface Magnetic Field Distributions of the White Dwarfs PG 1015+014 and HE 1045-0908
F. Euchner, S. Jordan, K. Reinsch +2
We have applied the method of Zeeman tomography to analyze the surface magnetic field structures of the white dwarfs PG 1015+014 and HE 1045-0908 from spin-phase resolved flux and…
New insights to the photometric structure of Blue Compact Dwarf Galaxies from deep Near-Infrared studies: II. The sample of northern BCDs
K. G. Noeske, P. Papaderos, L. M. Cairos +1
This paper is part of a series of publications which present a systematic study of Blue Compact Dwarf (BCD) Galaxies in the Near Infrared (NIR). Compared to the visible light, NIR…
Pox 186: an ultracompact galaxy with dominant ionized gas emission
N. G. Guseva, P. Papaderos, Y. I. Izotov +2
We present a ground-based optical spectroscopic and HST U, V, I photometric study of the blue compact dwarf (BCD) galaxy Pox 186. It is found that the emission of the low-surface b…
Deep VLT spectroscopy of the blue compact dwarf galaxies Tol 1214-277 and Tol 65
Y. I. Izotov, P. Papaderos, N. G. Guseva +2
We present VLT spectroscopic observations with different spectral resolutions and different slit orientations of the two metal-deficient blue compact dwarf (BCD) galaxies Tol 1214-…
AcDc - A new code for the NLTE spectral analysis of accretion discs: application to the helium CV AM CVn
T. Nagel, S. Dreizler, T. Rauch +1
We present a recently developed code for detailed NLTE calculations of accretion disc spectra of cataclysmic variables and compact X-ray binaries. Assuming a radial structure of a…
Stellar Populations of a Sample of Tidal Dwarf Galaxies
Peter M. Weilbacher, Uta Fritze-v. Alvensleben, Pierre-Alain Duc
We investigate the stellar populations of a sample of Tidal Dwarf Galaxies, combining observations and evolutionary synthesis models to try and reveal their formation mechanism. On…
