Astronomers Map Star Spots Using Tess and Kepler

Astronomers map star spots using Tess and Kepler

Scientists have devised a new method for mapping the spottiness of distant stars by using observations from NASA missions of orbiting planets crossing their stars' faces. The model builds on a technique researchers have used for decades to study star spots.

Astronomers Chart Stellar ‘Polka Dots’ with NASA’s TESS and Kepler

Astronomers have long grappled with the intricate patterns of stellar surfaces, which often complicate the interpretation of exoplanet observations. A transformative advancement in this realm emerges from a novel computational framework named StarryStarryProcess. This innovative model exploits data collected by NASA’s planet-hunting missions, enabling scientists to pinpoint the spatial distribution and characteristics of star spots — cooler, dar…
