Without using spectroscopic measurements, we aim at constraining if the possible atmospheres are hydrogen-rich or hydrogen-poor. We analyze the interiors of HD 219134 b and c, which are among the coolest super-Earths detected thus far. Harrison, A. Bonsor, T. Hands: “A new class of Super-Earths formed from high-temperature condensates: HD219134 b, 55 Cnc e, WASP-47 e”, MNRAS Barbara Vonarburg, Kommunikation und Öffentlichkeitsarbeit NCCR PlanetS und Universität Bern Science Writer: Site Editor: This star has a magnitude 9.4 optical companion at an angular separation of 106.6 arcseconds. Its discovery was announced in 2015. HD 219134 (also known as Gliese 892 or HR 8832) is a main-sequence star in the constellation of Cassiopeia. HD 219134 g, also known as HR 8832 g, is an unconfirmed exoplanet orbiting around the K-type star HR 8832 in the constellation of Cassiopeia.It has a minimum mass of 11 Earth Masses, suggesting that it could be a high-mass ocean planet or a Neptune-like ice giant.Unlike HD 219134 b and HD 219134 c it has not been observed by the Spitzer Space Telescope and thus its radius and density are unknown. It has a minimum mass of 11 Earth Masses, suggesting that it could be a high-mass ocean planet or a Neptune-like ice giant. PlanetS; Forschung. Its mass is 4.36 Earths, it takes 6.8 days to complete one orbit of its star, and is 0.0653 AU from its star. Its discovery was announced in 2015. Technologieplattform; Akademische Plattform (inkl.

HD 219134 b (or HR 8832 b) is one of at least five exoplanets orbiting HD 219134, a main-sequence star in the constellation of Cassiopeia.

Entdeckung. HD 219134 c, also known as HR 8832 c, is a hot, dense, rocky exoplanet orbiting around the K-type star HR 8832 in the constellation of Cassiopeia.Originally thought to be a little less than three times the mass of Earth, it is now known to be over 4 times the mass and 51% larger in radius, suggesting a rocky composition with a higher quantity of iron than Earth.
