Spectroscopic and photometric studies of low-metallicity star-forming dwarf galaxies. III. SBS 1415+437
N. G. Guseva, P. Papaderos, Y. I. Izotov +4
We present a detailed optical spectroscopic and B,V,I,Halpha photometric study of the metal-deficient cometary blue compact dwarf (BCD) galaxy SBS 1415+437. We derive an oxygen abu…
Spectroscopic and photometric studies of low-metallicity star-forming dwarf galaxies. II. HS 1442+4250
N. G. Guseva, P. Papaderos, Y. I. Izotov +4
We present broad-band V and I imaging and long-slit spectroscopy in the optical range 3600-7500A of the dwarf irregular galaxy HS 1442+4250. The oxygen abundance 12+log(O/H)=7.63+/…
Spectroscopic and photometric studies of low-metallicity star-forming dwarf galaxies. I. SBS 1129+576
N. G. Guseva, P. Papaderos, Y. I. Izotov +4
Spectroscopy and V,I CCD photometry of the dwarf irregular galaxy SBS 1129+576 are presented for the first time. The CCD images reveal a chain of compact H II regions within the el…
Zeeman tomography of magnetic white dwarfs: General method and application to EF Eridani
F. Euchner, K. Beuermann, K. Reinsch +3
We have developed a new method to derive the magnetic field distribution on the surfaces of rotating magnetic white dwarfs from phase-resolved flux and circular polarization spectr…
