The Stellar Content and Distance of UGC 4483
A. E. Dolphin, L. Makarova, I. D. Karachentsev +7
We present HST/WFPC2 observations of UGC 4483, an irregular galaxy in the M81/NGC 2403 complex. Stellar photometry was carried out with HSTphot, and is complete to V ~ 26.0 and I ~…
Irregular Magnetic Fields in Interstellar Clouds and the Linear Polarization of Starlight
D. S. Wiebe, W. D. Watson
Calculations are performed for the linear polarization of starlight due to extinction by aligned dust grains when the starlight traverses a medium with irregular magnetic fields. T…
Formation Mechanisms for Spirals in Barred Galaxies
Evgenii V. Polyachenko, Valerij L. Polyachenko
We consider a scenario of formation of the spiral structure in barred galaxies. This scenario includes the new non-resonant mechanism of elongation of spirals, due to the character…
Gas motions in the plane of the spiral galaxy NGC 3631
A. M. Fridman, O. V. Khoruzhii, E. V. Polyachenko +7
The velocity field of the nearly face-on galaxy NGC 3631, derived from observations in the H alpha line and the HI radio line, is analysed to study perturbations related to the spi…
The Core-Wing Anomaly of Cool Ap Stars: Abnormal Balmer Profiles
Charles R. Cowley, S. Hubrig, T. A. Ryabchikova +3
Paper by Cowley et al. The Core-Wing Anomaly Etc. The profiles of H in a number of cool Ap stars are anomalous. Broad wings, indicative of temperatures in the range 7000-8000K e…
Possible galactic sources of ultrahigh-energy cosmic rays and a strategy for their detection via gravitational lensing
Alexander Kusenko, Vadim A. Kuzmin
If decays of superheavy relic particles in the galactic halo are responsible for ultrahigh-energy cosmic rays, these particles must be clustered to account for small-scale anisotro…
A Giant Bipolar Shell around the WO star in the Galaxy IC 1613: Structure and Kinematics
V. L. Afanasiev, T. A. Lozinskaya, A. V. Moiseev +1
Observations of the nebula associated with the WO star in the galaxy IC 1613 are presented. The observations were carried out with a scanning Interferometer Fabry-Perot in H_alpha…
Energy Release on the Surface of a Rapidly Rotating Neutron Star during Disk Accretion: A Thermodynamic Approach
N. Sibgatullin, R. Sunyaev
The total energy E of a star as a function of its angular momentum J and mass M in the Newtonian theory: E = E(J, M) [in general relativity, the gravitational mass M of a star as a…
Optical and Infrared Spectroscopy of the type IIn SN 1998S : Days 3-127
A. Fassia, W. P. S. Meikle, N. Chugai +14
We present contemporary infrared and optical spectroscopic observations of the type IIn SN 1998S for the period between 3 and 127 days after discovery. In the first week the spectr…
Observation of X-ray lines from a Gamma-Ray Burst (GRB991216): Evidence of Moving Ejecta from the Progenitor
L. Piro, G. Garmire, M. Garcia +18
We report on the discovery of two emission features observed in the X-ray spectrum of the afterglow of the gamma-ray burst (GRB) of 16 Dec. 1999 by the Chandra X-Ray Observatory. T…
VLA HI Line Observations of the Extremely Metal-Poor Blue Compact Dwarf Galaxy SBS 0335-052
S. A. Pustilnik, E. Brinks, T. X. Thuan +2
We present the results of HI mapping with the NRAO VLA of one of the most metal-deficient blue compact dwarf (BCD) galaxies known, SBS 0335-052, with an oxygen abundance of only 1/…
Energy Release During Disk Accretion onto a Rapidly Rotating Neutron Star
N. R. Sibgatullin, R. A. Sunyaev
The energy release L_s on the surface of a neutron star (NS) with a weak magnetic field and the energy release L_d in the surrounding accretion disk depend on two independent param…
The population of close double white dwarfs in the Galaxy
Lev Yungelson, Gijs Nelemans, Simon. F. Portegies Zwart +1
We present a new model for the Galactic population of close double white dwarfs. The model accounts for the suggestion of the avoidance of a substantial spiral-in during mass trans…
The effect of projection on the observed gas velocity fields in barred galaxies
A. V. Moiseev, V. V. Mustsevoi
The problem of determining the pattern of gas motions in the central cases -- noncircular motions in the triaxial bar potential and motions in circular orbits but with orientation…
New class of low frequency QPOs: signature of nuclear burning or accretion disk instabilities?
M. Revnivtsev, E. Churazov, M. Gilfanov +1
We report the discovery of a new class of low frequency quasi--periodic variations of the X-ray flux in the X-ray bursters 4U1608-52 and 4U1636-536. We also report an occasional de…
Population synthesis for double white dwarfs I.Close detached systems
Gijs Nelemans, Lev R. Yungelson, Simon F. Portegies Zwart +1
We model the population of double white dwarfs in the Galaxy and find a better agreement with observations compared to earlier studies, due to two modifications. The first is the t…
