Researchers reveal effects of magnetic activity on mass transfer of binary
Algol-type binary systems consist of a B-A-F type main-sequence primary component and an F-G-K type giant or subgiant secondary component. According to the explanation of the Algol paradox, the initially more massive component evolves to fill the Roche lobes first and transfer material to another component, which results in the inversion of mass ratio and the formation of the Algol-type systems….
A Giant Black Hole Keeps Evading Detecting and Scientists Can’t Explain It
“An enormous black hole keeps slipping through astronomers’ nets…” reports Space.com: The big galaxy at the core of the cluster Abell 2261, which lies about 2.7 billion light-years from Earth, should have an even larger central black hole — a light-gobbling monster that weighs as much as 3 billion to 100 billion suns, astronomers estimate from the galaxy’s mass. But the…
