Forty-five new exoplanets discovered

Scientists have discovered a trove of forty-four planets in solar systems beyond our own in one go, dwarfing the usual number of confirmations from extrasolar surveys.

The findings will improve existing models of solar systems, and may help researchers investigate exoplanet atmospheres.

Astronomers pooled data from NASA’s Kepler and the ESA’s Gaia space telescopes. They confirmed existence of these 44 exoplanets and described various details about them

A portion of the findings yield some surprising characteristics.

“For example, four of the planets orbit their host stars in less than 24 hours,” said John Livingston, a graduate student at the University of Tokyo in Japan.

These contribute to a small but growing list of “ultrashort-period” planets, suggesting that they could be more common than previously believed. PTI
