Stellar Habitability In Our Neighbourhood
By Evan Gough (https://ift.tt/p7LmSlQ)

K-type stars, or orange dwarfs, are the Sun's slightly lower-mass cousins. Their long, stable lives mean they provide the conditions necessary for life to develop on exoplanets that orbit them. A new survey found thousands of them in our stellar neighbourhood and captured detailed spectra from them. These spectra tell astronomers a lot about their characteristics and the specific environments they create for their planets. Image Credit: Merikanto, CC 4.0

A new survey of K-type stars in the Sun's neighbourhood reveals important information about their ability to sustain their habitable zones. These stars are less massive, cooler, and dimmer than the Sun, but stay on the main sequence for many tens of billions of years. Their long lives can create the stable conditions necessary for life to develop on exoplanets.
