A stellar system with three super-Earths

Over 3500 extra-solar planets have been confirmed to date. Most of them were discovered using the transit method, and astronomers can combine the transit light curves with velocity wobble observations to determine the planet’s mass and radius, and thereby constrain its interior structure. An artist’s conception of an exoplanetary system, in this case around the star HD7924, that hosts two …Continue reading →
