Could the strange-looking irregular galaxies actually be remnants of the birth of galaxies? This paper demonstrates a method to find such galaxies.
A headline-grabbing paper calculated the prevalence of Earth-sized planets with long orbital periods around Sun-like stars. But are these planets anything like Earth?
Supernovae happen in the Milky Way at a rate of two or three per century. But, will we be able to see it when it happens next, or will dusty galactic center prevent us from studying it?
The IceCube project at the South Pole makes the first detection of high-energy extraterrestrial neutrinos.
In search of a good origin story for the building blocks of life, the authors of this paper have set their sights higher. Literally higher, to exoplanets’ skies.
In today’s paper, the authors study how the periods of two black hole x-ray binaries are changing. They find that the periods are decaying faster than expected based on standard theoretical arguments.
Cataclysmic variables are binary star systems where one of the stars—a white dwarf—devours its main sequence partner over time. Kepler proves yet again that it can find a lot more than just exoplanets by identifying a cataclysmic variable with a period of less than an hour.
Depending on how they scatter with nuclei, dark matter particles might affect the structure and evolution of our Sun.
Title: Evidence of an Asteroid Encountering a Pulsar Authors: P. R. Brook, A. Karastergiou, S. Buchner, S. J. Roberts, M. J. Keith, S. Johnson, R. M. Shannon First Author’s Institution: University of Oxford Pulsars- neutron stars formed during supernovae explosions- are often considered the “precision clocks” of radio astronomy. This is because of two fundamental properties observed from […]
Galactic bars have long been associated with many processes affecting galactic evolution. This paper studies how bars affect the star formation rate, mass and structure of a large sample of morphologically classified galaxies.
