Astronomers two giant newborn planets PDS 70 system
2020/5/29
New evidence confirms that first-ever pictures do capture the birth of a pair of planets orbiting the star PDS 70.Using a new infrared pyramid wavefront sensor for adaptive optics correction at the...
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...
Discovery of a stripped red giant core in a bright eclipsing binary system

We have identified a star in the WASP archive photometry with an unusual lightcurve due to the total eclipse of a small, hot star by an apparently normal A-type star and with an orbital period of only...
We show that the inclusion of an axion-like effective potential in the construction of a self-gravitating system made of scalar fields leads to a decrease on its compactness when the value of the self...

The current density in the dynamo region is estimated from thermospheric
neutral wind pattern and plasmaspheric electric field. The diurnal variation
of the meridional and the zonal component of the...
