ROTATIONAL SIGNATURE AND POSSIBLE r-MODE SIGNATURE IN THE GALLEX SOLAR NEUTRINO DATA
ROTATIONAL SIGNATURE POSSIBLE r-MODE SIGNATURE
2015/8/20
Recent analysis of the Homestake data has yielded evidence that the solar neutrino flux varies in time—more
specifically, that it exhibits a periodic variation that may be attributed to r...
The Radial Velocity Signature of Tides Raised in Stars Hosting Exoplanets
stars: planetary systems – stars: solar type – hydrodynamics – waves – planet-star interactions
2011/10/18
Close-in, massive exoplanets raise significant tides in their stellar hosts. We compute the radial velocity (RV) signal due to this fluid motion in the equilibrium tide approximation. The predicted ra...
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...
Kinematic signature of an intermediate-mass black hole in the globular cluster NGC 6388
black hole physics – globular cluster: individual (NGC 6388) – stars: kinematics and dynamics
2011/10/12
Intermediate-mass black holes (IMBHs) are of interest in a wide range of astrophysical fields. In particular, the possibility of finding them at the centers of globular clusters has recently drawn att...

2011/1/10
Within the universe, the astrophysical sites responsible for the production of radioactive 60Fe, of half life 2.62 Myr, are primarily confined to two: Type 1a supernovae and massive stars that end the...
Polarised foreground removal at low radio frequencies using rotation measure synthesis: Uncovering the signature of hydrogen reionisation

2010/11/12
Measurement of redshifted 21-cm emission from neutral hydrogen promises to be the most e ective method for studying the reionisation history of hydrogen and,indirectly, the rst galaxies. These studie...
Lyman `bump' galaxies - II. A possible signature of massive extremely metal-poor or metal-free stars in z=3.1 Ly-alpha emitters
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/29
Deep NB359 imaging with Subaru by Iwata et al. have detected surprisingly strong Lyman continuum (LyC; ~900A in the rest-frame) from some LAEs at z=3.1. However, the redshifts might be misidentified d...
A distinct peak-flux distribution of the third class of gamma-ray bursts: A possible signature of X-ray flashes?
High Energy Astrophysical Phenomena (astro-ph.HE) Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/28
Gamma-ray bursts are the most luminous events in the Universe. Going beyond the short-long classification scheme we work in the context of three burst populations with the third group of intermediate ...
