Study of Beta Equilibrated 2+1 Flavor Quark Matter in PNJL Model
Study of Beta Equilibrated 2+1 Flavor Quark Matter in PNJL Model
font style='font-size:12px;'>
2011/10/14
The QCD phase diagram of 2+1 flavour quark matter in $\beta$ equilibrium is studied within the framework of PNJL model. Signatures for first order phase transition can be seen in high baryon chemical ...
Starspots on the fastest rotators in the Beta Pic moving group

We carried out high-resolution spectroscopy and BV(I)_C photometric monitoring of the two fastest late-type rotators in the nearby Beta Pictoris moving group, HD199143 (F7V) and CD-641208 (K7V). The m...

Only for very few beta Cephei stars has the behaviour of the magnetic field been studied over the rotation cycle. During the past two years we have obtained multi-epoch polarimetric spectra of the bet...
Multi-Wavelength Modelling of the Beta Leo Debris Disc: 1, 2 or 3 planetesimal populations?
Multi-Wavelength Modelling Beta Leo Debris Disc planetesimal populations
font style='font-size:12px;'>
2011/9/27
In this paper we present a model of the Beta Leo debris disc, with an emphasis on modelling the resolved PACS images obtained as part of the Herschel key programme DEBRIS. We also present new SPIRE im...
Stellar and substellar mass function of the young open cluster candidates Alessi 5 and beta Monocerotis
Stellar substellar mass young open cluster candidates beta Monocerotis

2010/11/10
Although the stellar and substellar populations have been studied in various young and old open clusters, additional studies in clusters in the age range from 5 to 100Myr is crucial (e.g. to give more...
An investigation of the close environment of beta Cep with the VEGA/CHARA interferometer
Solar and Stellar Astrophysics (astro-ph.SR)
font style='font-size:12px;'>
2010/12/28
High-precision interferometric measurements of pulsating stars help to characterize their close environment. In 1974, a close companion was discovered around the pulsating star beta Cep using the spec...
Photometric study of two beta Cephei pulsators in eclipsing systems
Solar and Stellar Astrophysics (astro-ph.SR)
font style='font-size:12px;'>
2010/12/24
We present results of a photometric study of the young southern open cluster Stock 14. This cluster is known to contain two eclipsing systems with presumed beta Cephei components, HD 101794 and HD 101...
