| A rocky planet in a ~17 hour orbit around a sunlike star, characterised by K2 and HARPS-N. Estimated dayside temperature ~3480 K. Frustagli et al. "An ultra-short period rocky super-Earth orbiting the G2-star HD 80653" https://arxiv.org/abs/2001.02217There are hints of curvature in the RV residuals, which might indicate the presence of an additional ~0.35–0.50 Jupiter mass planet in a ~260–400 day orbit. | |
