Abstract | We report the discovery and characterization of a transiting warm sub-Neptune planet around the nearby bright (V = 8.75 mag, K = 7.15 mag) solar twin HD 183579, delivered by the Transiting Exoplanet Survey Satellite (TESS). The host star is located 56.8 +/- 0.1 pc away with a radius of R-* = 0.97 +/- 0.02R(circle dot) and a mass of M-* = 1.03 +/- 0.05M(circle dot). We confirm the planetary nature by combining space and ground-based photometry, spectroscopy, and imaging. We find that HD 183579b (TOI-1055b) has a radius of R-p = 3.53 +/- 0.13R(circle plus) on a 17.47 d orbit with a mass of M-p = 11.2 +/- 5.4M(circle plus) (3 sigma mass upper limit of 27.4M(circle plus)). HD 183579b is the fifth brightest known sub-Neptune planet system in the sky, making it an excellent target for future studies of the interior structure and atmospheric properties. By performing a line-by-line differential analysis using the high-resolution and signal-to-noise ratio HARPS spectra, we find that HD 183579 joins the typical solar twin sample, without a statistically significant refractory element depletion. |
