A SEARCH FOR RADIO PULSARS IN THE NORTHERN SKY: DISCOVERY OF A PULSAR IN A UNIQUE BINARY SYSTEM
Search Radio pulsar The sky The pulsar. A binary system
2014/12/10
A sensitive search for pulsars has been conducted using the 92-meter transit telescope of the National Radio Astronomy Observatory. Nearly 50% of the sky north of +20(DEGREES) declination was searched...
Elemental abundance differences in the 16 Cygni binary system: a signature of gas giant planet formation?
Elemental abundance differences signature planet formation
2011/10/20
The atmospheric parameters of the components of the 16Cygni binary system, in which the secondary has a gas giant planet detected, are measured accurately using high quality observational data. Abunda...
Multi-wavelength observations of the young binary system Haro 6-10: The case of misaligned discs
Binary stars - Star Formation - Haro 6-10
2011/10/17
Context. We present a multi-wavelength, high-resolution observational survey of the young binary system Haro 6-10 (GV Tau, IRAS 04263+2426), which is harbouring one of the few known infrared companion...
Modelling interaction of relativistic and non-relativistic winds in binary system PSR B1259-63/SS2883 - II. Impact of magnetization and anisotropy of the pulsar wind
HD – shock waves - pulsars: binaries
2011/10/19
In this paper, we present a numerical study of the properties of the flow produced by the collision of a magnetized anisotropic pulsar wind with its environment in binary system. We compare the impact...
Discovery of a stripped red giant core in a bright eclipsing binary system
binaries: spectroscopic – binaries: individual: KOI-81 – stars: individual 1SWASP J024743.37− 251549.2
2011/10/19
We have identified a star in the WASP archive photometry with an unusual lightcurve due to the total eclipse of a small, hot star by an apparently normal A-type star and with an orbital period of only...
Radio Imaging of the NGC 1333 IRAS 4A Region: Envelope, Disks, and Outflows of a Protostellar Binary System
ISM: individual (NGC 1333 IRAS 4A) — ISM: jets outfl ows — ISM: binaries: general— stars: formation
2011/10/12
The NGC 1333 IRAS 4A protobinary was observed in the 1.3 cm and 6.9 mm continuum and the ammonia and SiO lines, with an angular resolution of about 0.4 arcseconds. The continuum maps show the circumst...

Theoretical Spectra Binary System Effects Irradiation Donor Stars
2011/9/29
Taking into account a range of parameters determined from the evolutionary models and available observational data, the detailed non-LTE spectra for the primary star and the irradiated donor star in t...

Marginally ratio close binary V1191 Cyg
2011/9/27
In this study, we present photometric and spectroscopic variations of the extremely small mass ratio ($q\simeq 0.1$) late-type contact binary system \astrobj{V1191 Cyg}. The parameters for the hot and...

2011/9/27
In this study we determined precise orbital and physical parameters of the very short period low-mass contact binary system CC Com. The parameters are obtained by analysis of the new CCD data with the...
Black Hole in Binary System is the Source of Cosmic Gamma-Ray Bursts and Their Counterparts
Accretion Disks, Binaries, Black Hole Physics, Gamma-Rays Bursts, Relativity
2011/9/15
Discovery of GRB clusters allows us to determine coordinates and characteristics of their sources. The objects radiating GRBs are reliably identified with black hole binaries, including the Galactic b...
Modeling of the Vela complex including the Vela supernova remnant, the binary system gamma2 Velorum, and the Gum nebula
ISM supernova remnants – ISM clouds – ISM bubbles – ISM individual objects Vela SNR shock waves Stars
2010/11/11
We study the geometry and dynamics of the Vela complex including the Vela supernova remnant (SNR), the binary system γ2 Velorum and the Gum nebula. We show that the Vela SNR belongs to a subclass of n...
Evidence for gamma-ray emission from the low-mass X-ray binary system FIRST J102347.6+003841
