Accretion in the detached post-common-envelope binary LTT 560
binaries: close – Stars: late-type – white dwarfs – Stars: individual: LTT 560 – cataclysmic variables
2011/10/11
In a previous study, we found that the detached post-common-envelope binary LTT 560 displays an Halpha emission line consisting of two anti-phased components. While one of them was clearly caused by s...
The Role of Tiny Grains on the Accretion Process in Protoplanetary Disks
Tiny Grains Accretion Process Protoplanetary Disks
2011/10/9
Tiny grains such as PAHs have been thought to dramatically reduce the coupling between gas and magnetic fields in weakly ionized gas such as in protoplanetary disks (PPDs) because they provide tremend...

Instability Driven Accretion Protoplanetary
2011/10/9
The gas dynamics in protoplanetary disks (PPDs) is strongly affected by non-ideal MHD effects. Using a complex chemical reaction network with standard prescriptions for X-ray and cosmic-ray ionization...
Optical and Near-IR long-term monitoring of NGC3783 and MR2251-178: evidence for variable near-IR emission from thin accretion discs
Seyfert galaxies:general — Seyfert galaxies:individual(NGC 3783,MR 2251-178)
2011/9/26
We present long term near-IR light curves for two nearby AGN: NGC3783 and MR2251-178. The near-IR data are complemented with optical photometry obtained over the same period of time. The light curves ...

2009/5/12
We use the method introduced by Karami & Mohebi (2007), and Karami & Teimoorinia (2007) which enable us to derive the orbital parameters of the spectroscopic binary stars by the nonlinear least square...
