TESS discovery of a super-Earth and three sub-Neptunes hosted by the bright, Sun-like star HD 108236
We report the discovery and validation of four extrasolar planets hosted by the nearby, bright, Sun-like (G3V) star HD~108236 using data from the Transiting Exoplanet Survey Satellite (TESS). We present transit photometry, reconnaissance and precise Doppler spectroscopy as well as high-resolution im...

| description | We report the discovery and validation of four extrasolar planets hosted by the nearby, bright, Sun-like (G3V) star HD~108236 using data from the Transiting Exoplanet Survey Satellite (TESS). We present transit photometry, reconnaissance and precise Doppler spectroscopy as well as high-resolution imaging, to validate the planetary nature of the objects transiting HD~108236, also known as the TESS Object of Interest (TOI) 1233. The innermost planet is a possibly-rocky super-Earth with a period of \(3.79523_{-0.00044}^{+0.00047}\) days and has a radius of \(1.586\pm0.098\) \(R_\oplus\). The outer planets are sub-Neptunes, with potential gaseous envelopes, having radii of \(2.068_{-0.091}^{+0.10}\) \(R_\oplus\), \(2.72\pm0.11\) \(R_\oplus\), and \(3.12_{-0.12}^{+0.13}\) \(R_\oplus\) and periods of \(6.20370_{-0.00052}^{+0.00064}\) days, \(14.17555_{-0.0011}^{+0.00099}\) days, and \(19.5917_{-0.0020}^{+0.0022}\) days, respectively. With V and K\(_{\rm s}\) magnitudes of 9.2 and 7.6, respectively, the bright host star makes the transiting planets favorable targets for mass measurements and, potentially, for atmospheric characterization via transmission spectroscopy. HD~108236 is the brightest Sun-like star in the visual (V) band known to host four or more transiting exoplanets. The discovered planets span a broad range of planetary radii and equilibrium temperatures, and share a common history of insolation from a Sun-like star (\(R_\star = 0.888 \pm 0.017\) R\(_\odot\), \(T_{\rm eff} = 5730 \pm 50\) K), making HD 108236 an exciting, opportune cosmic laboratory for testing models of planet formation and evolution. |

extrasolar planets hosted by the nearby, bright, Sun-like (G3V) star HD~108236 using data from the Transiting Exoplanet Survey Satellite (TESS). We present transit photometry, reconnaissance and precise Doppler spectroscopy as well as high-resolution imaging, to validate the planetary nature of the objects transiting HD~108236, also known as the TESS Object of Interest (TOI) 1233. The innermost planet is a possibly-rocky super-Earth with a period of \(3.79523_{-0.00044}^{+0.00047}\) days and has a radius of \(1.586\pm0.098\) \(R_\oplus\). The outer planets are sub-Neptunes, with potential gaseous envelopes, having radii of \(2.068_{-0.091}^{+0.10}\) \(R_\oplus\), \(2.72\pm0.11\) \(R_\oplus\), and \(3.12_{-0.12}^{+0.13}\) \(R_\oplus\) and periods of \(6.20370_{-0.00052}^{+0.00064}\) days, \(14.17555_{-0.0011}^{+0.00099}\) days, and \(19.5917_{-0.0020}^{+0.0022}\) days, respectively. With V and K\(_{\rm s}\) magnitudes of 9.2 and 7.6, respectively, the bright host star makes the transiting planets favorable targets for mass measurements and, potentially, for atmospheric characterization via transmission spectroscopy. HD~108236 is the brightest Sun-like star in the visual (V) band known to host four or more transiting exoplanets. The discovered planets span a broad range of planetary radii and equilibrium temperatures, and share a common history of insolation from a Sun-like star (\(R_\star = 0.888 \pm 0.017\) R\(_\odot\), \(T_{\rm eff} = 5730 \pm 50\) K), making HD 108236 an exciting, opportune cosmic laboratory for testing models of planet formation and evolution.</abstract><cop>Ithaca</cop><pub>Cornell University Library, arXiv.org</pub><doi>10.48550/arxiv.2004.11314</doi><oa>free_for_read</oa></addata></record> |
