Acceleration of particles by rotating black holes: near-horizon geometry and kinematics
Acceleration particles rotating black holes: near-horizon geometry kinematics
2011/10/14
Nowadays, the effect of infinite energy in the centre of mass frame due to near-horizon collisions attracts much attention.We show generality of the effect combining two seemingly completely different...
Star Clusters in M31: Old Clusters with Bar Kinematics
catalogs – galaxies individual (M31) – galaxies star clusters – globular clusters
2010/11/12
We analyze our accurate kinematical data for the old clusters in the inner regions of M31. These velocities are based on high S/N Hectospec data (Caldwell et al 2010). The data are well suited for ana...
Formation and evolution of dwarf early-type galaxies in the Virgo cluster I. Internal kinematics
Galaxies clusters individual Virgo Galaxies dwarf Galaxies elliptical and lenticular cD Galaxies
2010/11/12
We present new medium resolution kinematic data for a sample of 21 dwarf early-type galaxies (dEs) mainly in the Virgo cluster,obtained with the WHT and INT telescopes at the Roque de los Muchachos Ob...
Local Stellar Kinematics from RAVE Data: I. Local Standard of Rest
Galaxy kinematics and dynamics solar neighbourhood solar motion local standard of rest stellar content
2010/11/11
We analyze a sample of 82850 stars from the RAVE survey, with well-determined velocities and stellar parameters, to isolate a sample of 18026 high-probability thin-disc dwarfs within 600 pc of the Sun...
Millimeter imaging of MWC 758: probing the disk structure and kinematics
Solar and Stellar Astrophysics (astro-ph.SR) Earth and Planetary Astrophysics (astro-ph.EP)
2011/1/5
We investigate the structure and kinematics of the circumstellar disk around the Herbig Ae star MWC 758 using high resolution observations of the 12CO (3-2) and dust continuum emission at the waveleng...
Kinematics of the Ammonia Disk around the Protostar NGC 1333 IRAS 4A2
Galaxy Astrophysics (astro-ph.GA)
2010/12/28
The NGC 1333 IRAS 4A protobinary was observed in the ammonia (2, 2) and (3, 3) lines with an angular resolution of 0.3 arcsec. The ammonia emission source of IRAS 4A2 is elongated in the direction per...
Solar Wind Drag and the Kinematics of Interplanetary Coronal Mass Ejections
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
Coronal mass ejections (CMEs) are large-scale ejections of plasma and magnetic field from the solar corona, which propagate through interplanetary space at velocities of $\sim$100--2500~km~s$^{-1}$.
