Revisiting the Barnard’s Star Debate
A possible super-Earth was discovered 6 light years from us around Barnard’s star, but does it actually exist?
The Tortoise and the Star
Spectrographs here on Earth are getting good enough to detect tortoise-speed velocity shifts in starlight. That means that we need to understand the bubbling, broiling surfaces of stars to tortoise-level precision.
The Jupiter Analog Companions to Super-Earths
Today’s authors search for Jupiter analogs in foreign star systems to see how these giant worlds might affect the development of planets closer to the sun.
Choosing targets with TESS
With the launch of TESS, we will soon have many more exoplanet candidates. But how do we determine which are the most valuable for follow-up observations?
Not Quite a Star, Not Quite a Planet: A Planetary-Mass Object in AB Dor
In or out? Today’s paper explores whether or not an unusual object belongs to the AB Doradus moving group—and what it means if it does.
Is S0-2 a Binary Star?
When it zips past the Galactic Center black hole in 2018, how would a possible binarity of the star S0-2 affect the detectability of its relativistic motion?
