IY UMa: accretion disc evolution after superoutburst

V. Stanishev, Z. Kraicheva, H. M. J. Boffin +1

CCD photometry of the newly discovered eclipsing dwarf nova IY UMa is used to study the physical properties of the accretion disc in the late decline and quiescence stages. Eclipse…

Comparison of the H-alpha circumstellar disks in Be/X-ray binaries and Be stars

R. K. Zamanov, P. Reig, J. Marti +4

We present a comparative study of the circumstellar disks in Be/X-ray binaries and isolated Be stars based upon the H-alpha emission line. From this comparison it follows that the…

Kinematics of the ionized gas in the Local Group irregular galaxy IC 1613

M. Valdez-Gutierrez, M. Rosado, L. Georgiev +2

We present Halpha and [SII] observations for the Local Group irregular galaxy IC 1613 using the PUMA scanning Fabry-Perot interferometer. Our goal is to analyze the kinematics of t…

The Red Stellar Contents of Three Selected Fields of The Local Group Dwarf Irregular Galaxy IC1613

J. Borissova, L. Georgiev, R. Kurtev +4

We present a moderately-deep JK photometry for three selected areas of the dwarf irregular galaxy IC1613. The color-magnitude diagrams contain a mixture of red supergiants, asympto…

The outer-halo globular cluster NGC 6229. IV. Variable stars

J. Borissova, M. Catelan, T. Valchev

We present time-series B, V photometry of NGC 6229, obtained with the purpose of providing the first extensive CCD variability study of this cluster. As a result, we were able to o…

Saving Astronomical Treasures

Noah Brosch, Rene Hudec, Peter Kroll +1

The time domain is under-exploited in an astrophysical context, because the large photographic plate collections are almost never consulted by young astronomers. This is a result o…

Correlated V/R and IR photometric variations in the Be/X-ray binary LS I +61 235/RX J0146.9+6121

P. Reig, I. Negueruela, M. J. Coe +3

We report on the long-term variability of the Be/X-ray binary LS I +61 235/RX J0146.9+6121. New optical spectroscopic and infrared photometric observations confirm the presence of…

Near Infrared Photometry of Galactic Globular Clusters M56 and M15. Extending the Red Giant Branch vs. Metallicity Calibration Towards Metal Poor Systems

Valentin D. Ivanov, Jordanka Borissova, Almudena Alonso-Herrero +1

Infrared JKs-band photometry of the Galactic globular clusters M15 and, for the first time, M56 is presented. We estimated the reddening (E(B-V)=0.18+/-0.08 mag) and distance modul…

Magnetic field and unstable accretion during AM Herculis low states

J. M. Bonnet-Bidaud, M. Mouchet, N. M. Shakhovskoy +6

A study of AM Her low states in September 1990 and 1991 and June-July 1997 is reported from a coordinated campaign with observations obtained at the Haute-Provence observatory, at…
