Stellar activity can mimic misaligned exoplanets

The occultation of stellar active regions during the planetary transit can lead to inaccurate estimates of the characteristics of these exoplanets, especially the spin-orbit tilt angle. This was the conclusion of simulations ...

Pulverized planet dust might lie around double stars

(PhysOrg.com) -- Tight double-star systems might not be the best places for life to spring up, according to a new study using data from NASA's Spitzer Space Telescope. The infrared observatory spotted a surprisingly large ...

Planet 'devoured in secret' by its own sun

(Phys.org)—A planet roughly 1.4 times the size of Jupiter is being consumed by its own star behind a shroud thanks to a magnesium veil absorbing all of certain light wavelengths, according to new observations by the Hubble ...

A stellar achievement: Magnetized space winds in the laboratory

New insights have been gained about stellar winds, streams of high-speed charged particles called plasma that blow through interstellar space. These winds, created by eruptions from stars or stellar explosions, carry with ...
