Observations and light curve solutions of ultrashort-period eclipsing binaries
Diana P. Kjurkchieva, Dinko P. Dimitrov, Sunay I. Ibryamov +1
Photometric observations in V and I bands and low-dispersion spectra of ten ultrashort-period binaries (NSVS 2175434, NSVS 2607629, NSVS 5038135, NSVS 8040227, NSVS 9747584, NSVS 4…
Long-term photometric observations in the field of the star formation region NGC7129
Evgeni Semkov, Stoyanka Peneva, Sunay Ibryamov +1
We present results from long-term optical photometric observations of the Pre-Main Sequence (PMS) stars, located in the star formation region around the bright nebula NGC 7129. Usi…
X-rays from the colliding wind binary WR 146
Svetozar A. Zhekov
The X-ray emission from the massive binary WR 146R is analysed in the framework of the colliding stellar wind (CSW) picture. The theoretical CSW model spectra match well the shape…
The magnetic strip(s) in the advanced phases of stellar evolution - Theoretical convective turnover timescale and Rossby number for low- and intermediate-mass stars up to the AGB at various metallicities
C. Charbonnel, T. Decressin, N. Lagarde +7
Recent spectropolarimetric observations of otherwise ordinary G, K, and M giants revealed localized magnetic strips in the HRD coincident with the regions where the first dredge-up…
Asteroseismology of the {\it Kepler} target KIC\,9204718
C. Ulusoy, I. Stateva, I. Kh. Iliev +2
The high precision data obtained by the {\it Kepler} satellite allows us to detect hybrid type pulsator candidates more accurately than the data obtained by ground-based observatio…
Discovery of optical flickering from the symbiotic star EF Aquilae
R. K. Zamanov, S. Boeva, Y. M. Nikolov +9
We report optical CCD photometry of the recently identified symbiotic star EF Aql. Our observations in Johnson V and B bands clearly show the presence of stochastic light variation…
Observations and light curve solutions of the W UMa binaries V796 Cep, V797 Cep, CSS J015341.9+381641 and NSVS 3853195
D. P. Kjurkchieva, V. A. Popov, S. I. Ibryamov +2
Photometric observations in Sloan g' and i' bands of four W UMa binaries, V796 Cep, V797 Cep, CSS J015341.9+381641 and NSVS 3853195, are presented. Our observations showed that CSS…
