Astronomers confirm existence of two giant, newborn planets in PDS 70 system（图）
Astronomers two giant newborn planets PDS 70 system
2020/5/22
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...

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...
We examine the existence of relativistic stars in f(T) modified gravity and explicitly construct several classes of static perfect fluid solutions. We derive the conservation equation from the complet...
Existence of Equilibrium Points and their Linear Stability in the Generalized Photogravitational Chermnykh-Like Problem with Power-law Profile
Existence of Equilibrium Points and their Linear Stability in the Generalized Photogravitational Chermnykh-Like Problem with Power-law Profile
2011/10/14
We consider the modified restricted three body problem with power-law density profile of disk, which rotates around the center of mass of the system with perturbed mean motion. Using analytical and nu...
CO-EXISTENCE OF TWO PLASMA PHASES IN SOLAR AND AGN CORONAS
Active Galactic Nuclei CO-EXISTENCE
2009/3/26
Here we have juxtaposed two distant cosmic locations of the Sun
and AGN where neutral hydrogen appears in a close connection with hot coronas.
Besides the solar photosphere, chromosphere and promine...
