Planet Formation in Earth-like Orbit around a Young Star
Planet Formation Earth Young Star
2016/4/13
The disks of dust and gas that surround young stars are the formation sites of planets. New images from the Atacama Large Millimeter/submillimeter Array (ALMA) reveal never-before-seen detai...

Giant Planets Carving Paths Four Young Stars ALMA
2015/12/22
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found the clearest evidence yet that giant planets have recently formed around four young stars. These new worlds, each p...
Perturbed stellar motions around the rotating black hole in Sgr A* for a generic orientation of its spin axis
Perturbed stellar motions rotating black hole generic orientation spin axis
2011/10/17
Empirically determining the averaged variations of the orbital parameters of the stars orbiting the Supermassive Black Hole (SBH) hosted by the Galactic Centre (GC) in Sgr A* is, in principle, a valua...
Habitability of Super-Earth Planets around Main-Sequence Stars including Red Giant Branch Evolution: Models based on the Integrated System Approach
Main-Sequence Stars including Red Giant Branch Evolution Models based Integrated System Approach
2011/10/20
In a previous study published in Astrobiology, we focused on the evolution of habitability of a 10 M_E super-Earth planet orbiting a star akin to the Sun. This study was based on a concept of planetar...
On the Detection of (Habitable) Super-Earths Around Low-Mass Stars Using Kepler and Transit Timing Variation Method
Planetary Systems
2011/10/9
We present the results of an extensive study of the detectability of Earth-sized planets and super-Earths in the habitable zones of cool and low-mass stars using transit timing variation method. We ha...
Massive star formation around I05345+3157 -- I. The dense gas
infrared:associations: individual (IRAS05345+3157) – radio continuum:interferometric
2011/9/29
We present observations of the intermediate to massive star-forming region I05345+3157 using the molecular line tracer CS(2-1) with CARMA to reveal the properties of the dense gas cores. Seven gas cor...
Mid-infrared interferometric monitoring of evolved stars - The dust shell around the Mira variable RR Aql at 13 epochs
Techniques:interferometric – Stars:AGB – Stars:atmospheres – Stars:mass loss – Stars:individual:RR Aql
2011/9/28
We obtained 13 epochs of mid-infrared interferometry with the MIDI instrument at the VLTI between April 2004 and July 2007, covering pulsation phases 0.45-0.85 within four cycles. The data are modeled...

Ultracool stars take 'wild rides' around, outside the Milky Way
Ultracool stars 'wild rides' around the Milky Way
2009/6/12
Astronomers announced today that stars of a recently discovered type, dubbed ultracool subdwarfs, take some pretty wild rides as they orbit around the Milky Way, following paths that are very differen...
Magnetic turbulence in and around the Earth's magnetosphere
Magnetic turbulence Earth's magnetosphere
2009/5/27
Magnetic turbulence is found in most space plasmas, including the geospace environment. Recent spacecraft observations of magnetic turbulence in the ion foreshock, in the magnetosheath, in the polar ...
