Optical characterization of two cataclysmic variables: RBS 0490 and SDSS J075939.79+191417.3

Arti Joshi, J. C. Pandey, Nikita Rawat +3

We present optical photometric and spectroscopic observations of two Cataclysmic Variables (CVs), namely RBS 0490 and SDSS J075939.79+191417.3. The optical variations of RBS 0490 h…

First detection of a magnetic field in low-luminosity B[e] stars: New scenarios for the nature and evolutionary stages of FS CMa stars

D. Korcakova, F. Sestito, N. Manset +8

We report the first detection of the magnetic field in a star of FS CMa type, a subgroup of objects characterized by the B[e] phenomenon. The split of magnetically sensitive lines…
