Researchers offer look central engine powering solar flare
2020/7/31
In a U.S. National Science Foundation-funded study published in Nature Astronomy, an international team of researchers has presented a new, detailed look inside the "central engine" of a lar...
Energy is the most important requirement for life. It can be acquired by harvesting electrons flowing naturally from reduced to oxidized inorganic compounds (lithotrophy) or organic compounds (organot...
The Na D profiles of nearby low-power radio sources: Jets powering outflows
galaxies: active — galaxies:radio continuum — galaxies:ISM
2011/9/28
We have analyzed the properties of the Na D doublet lines in a large sample of 691 radio galaxies using the Sloan Digital Sky Survey (SDSS). These radio galaxies are resolved in the FIRST survey, have...
Common Powering Mechanism of Intermediate Luminosity Optical Transients and Luminous Blue Variables
winds outflows— stars mass loss— stars vari-ables other — supernovae general
2010/11/11
We study recent Intermediate Luminosity Optical Transients (ILOTs) and major eruptions of Luminous Blue Variables (LBVs), and strengthen claims for a similar powering mechanism. We study new ILOTs and...
Right now, 10 to 15 Rubik’s Cube-sized satellites are orbiting high above Earth. Known as cube satellites, or “CubeSats,” the devices help researchers conduct simple space observations and measure cha...
