An unlikely survivor: a low-density hot Neptune orbiting a red giant star

By Samuel Grunblatt and others
Hot Neptunes, gaseous planets smaller than Saturn (\sim 3-8 R_\oplus) with orbital periods less than 10 days, are rare. Models predict this is due to high-energy stellar irradiation stripping planetary atmospheres over time, often leaving behind only rocky planetary cores. We present the discovery of a 6.2 R_\oplus(0.55 R_\mathrm{J}), 19.2... Show more
