There’s a lot going on in the HD 142527 protoplanetary disk — accretion, gap opening, and a horseshoe-shaped dust ring. The authors of this paper used ALMA to take a closer look at the gas and dust in this busy disk.
Shapiro time delays are one of the four tests of general relativity possible in the solar system. Astronomers can use these timing delays to measure properties of binary pulsar systems.
Seven gas clouds have been found in the region between two galaxies. Are they part of a intergalactic filament or remnants from a past galaxy interaction?
Faigler et al. apply their BEER algorithm to a collection of stars in the Kepler field and find a hot Jupiter missed by the Kepler Science Team, showing a new way to find and characterize planets without follow-up observations.
The authors present the discovery of a new hot carbon-atmosphere white dwarf with a strong magnetic field. This discovery might help illuminate the origins of a recently found class of white dwarfs.
It’s big, it’s active, and it’s only 20 million lightyears away– it is the Whirlpool galaxy, and astronomers are getting a brand new view. Using the Plateau de Bure interferometer, this paper examines the gas in this nearby grand-design spiral galaxy on arcsecond scales, resolving for the first time its individual molecular clouds. What does this tell us about star formation in this galaxy? Stay tuned!
