The Electron Capture Decay of 163-Ho to Measure the Electron Neutrino Mass with sub-eV Accuracy and Beyond
electron neutrino mass electron capture decay 163Ho
2012/2/24
We have investigated the possibility of measuring the electron neutrino mass with sub-eV sensitivity by studying the electron capture decay of 163-Ho with cryogenic microcalorimeters. In this paper we...
Mass segregation and fractal substructure in young massive clusters: (I) the McLuster code and method calibration
galaxies: star clusters: individual: R136 — galaxies: star formation —methods: data analysis — Magellanic Clouds
2011/10/8
By analysing models of the young massive cluster R136 in 30 Doradus, set-up using the herewith introduced and publicly made available code McLuster, we investigate and compare different methods for de...
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...
Short Gamma-ray Bursts: the mass of the accretion disk and the initial radius of the outflow
Short Gamma-ray Bursts:accretion disk initial radius outflow
2011/10/9
In this work we estimate the accretion-disk mass in the specific scenario of binary-neutron-star-merger with current observational data. Assuming that the outflows of short Gamma-ray Bursts (GRBs) are...
Marginally low mass ratio close binary system V1191 Cyg
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...
The short-period low-mass binary system CC Com revis
stars binaries:close stars:individual (CC Com) stars:low-mass stars:evolution
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...
Analytical Treatment of the Two-Body Problem with Slowly Varying Mass
Mass loss—binary systems—two-body problem—perturbations.
2010/9/15
The present work is concerned with the two-body problem with varying mass in case of isotropic mass loss from both components of the binary systems. The law of mass variation used gives rise to a pert...
