Protostar Blazes Bright,Reshaping Its Stellar Nursery
Protostar Blazes Bright Reshaping Stellar Nursery
2017/3/30
A massive protostar, deeply nestled in its dust-filled stellar nursery, recently roared to life, shining nearly 100 times brighter than before. This outburst, apparently triggered by an avalanche...
Dust grains could be remnants of stellar explosions billions of years ago
Dust grains remnants stellar explosions billions
2016/3/21
Microscopic dust particles have been found in meteoritic material on Earth, particles that were likely formed in stellar explosions that occurred long before the creation of our star, the sun.Whether ...

When stellar center gasification substance thermal expansion force is greater than stellar center minimum pressure, from stellar center, pressure minimal two symmetrical directions, jet out two shares...
On using the beaming effect to measure spin-orbit alignment in stellar binaries with Sun-like components
measure spin-orbit alignment stellar binaries Sun-like components
2011/10/13
The beaming effect (aka Doppler boosting) induces a variation in the observed flux of a luminous object, following its observed radial velocity variation. We describe a photometric signal induced by t...
Rossby waves and polar spots in rapidly rotating stars: Implications for stellar wind evolution
magnetic fi eld – Stars: activity – Stars: starspots – Stars: oscillations – Physical data and processes: Magnetohydrodynamics
2011/10/10
Rapidly rotating stars show short-period oscillations in magnetic activity and polar appearance of starspots. The aim of this paper is to study large-scale shallow water waves in the tachoclines of ra...
Helicity and dynamo action in magnetized stellar radiation zones
magnetohydrodynamics (MHD) – instabilities – stars: magnetic fi elds – stars: interiors
2011/10/8
Helicity and \alpha effect driven by the nonaxisymmetric Tayler instability of toroidal magnetic fields in stellar radiation zones are computed. In the linear approximation a purely toroidal field alw...
Computational Developments for Distance Determination of Stellar Groups
Distance determination spectral type frequency function
2010/9/15
In this paper, we consider a statistical method for distance determination of stellar groups. The method depends on the assumption that the members of the group scatter around a mean absolute magnitud...
Entropy Maximization, Cutoff Distribution, and Finite Stellar Masses

2009/9/4
Conventional equilibrium statistical mechanics of open gravitational systems is known to be problematical. We first recall that spherical stars/galaxies acquire unbounded radii, become infinitely mass...
