Continuums seem to be the name of the game in astronomy. On more than one occasion, astronomers have defined discrete subclasses for a type of phenomena only to later discover objects which populate an intermediate space between their original classifications. So… what about black holes?
We can use galaxy clusters for many different science goals, but first we need to figure out where they are.
Wolfgang & Laughlin combine observations from the HARPS radial velocity survey and the Kepler transit survey to investigate the mass-radius-period distribution of exoplanets. They find that most small planets are rocky.
I’m here at the Extreme Solar Systems 2 conference in Jackson Hole, Wyoming. On Monday, Sarah Ballard spoke about recent results on the Kepler-19 system; she led a paper on this object that was posted to the arxiv last week. This is the story of the newly-discovered transiting planet Kepler-19b and its mysterious companion.
Astronomers have discovered an extremely metal-poor, low mass star located in the Galactic Halo. SDSS J102915+172927 appears to have fewer metals than ever predicted for stars of this mass since many models of star formation suggest that a star with these properties should not have even formed in the early universe.
The 2017 solar eclipse will provide a unique opportunity to launch some exciting citizen science. This white paper describes how!
