By looking at the spectral changes of the accretion disk emission around black holes, we can trace the physical changes of the accreting material.
Astronomers are hearing a new type of radio transient, but no one knows where they come from and how they are created. This paper suggests one of the six documented Fast Radio Bursts detected so far originated close to home, within our own galaxy.
Tune in now for the first extrasolar weather map of a nearby brown dwarf, made using Doppler imaging.
Most binary stars probably formed at the same time, meaning all stars in the same system should have the same age. The authors of this paper analyze a stellar binary system where one star appears to be lying about its age, as one star appears 3 billion years older than its companion.
Small and massive compact galaxies are some of the hardest galaxies to find, but they could potentially reveal how galaxies evolved in the early universe.
By examining their expansion rate over time, Type II supernovae provide a way to measure extragalactic distances.
A new debris disk is discovered by the Herschel Space Telescope around the red dwarf tertiary star in the famous Fomalhaut system.
The Crab Nebula ups its game when it’s found to host the first molecule containing a noble gas to be found in space.
From measurements of quasar spectra, we can determine whether or not the fine structure constant is really a constant.
Title: Fast Radio Bursts May Originate from Nearby Flaring Stars Authors: Abraham Loeb, Yossi Shvartzvald, Dan Maoz First Author’s Institution: Institute for Theory and Computation, Harvard University Paper Status: MNRAS, in press One of the most intriguing discoveries in radio astronomy in recent years has been the discovery of Fast Radio Bursts (FRBs). Originally called Lorimer bursts after the […]
