Without using spectroscopic measurements, we aim at constraining if the possible atmospheres are hydrogen-rich or hydrogen-poor. Abstract. HD 219134 c is a Super-Earth exoplanet that orbits a K-type star. Anya Biferno. [15][note 1][16] A total of four independent studies have been done regarding the planetary system of HD 219134, with some of their results conflicting with each other. HD 219134 c, còn được gọi là HR 8832 c, là một ngoại hành tinh đất đá nóng, dày đặc, quay quanh ngôi sao loại K HR 8832 trong chòm sao Tiên Hậu (Cassiopeia). Its mass is about 4.36 times Earth’s, it takes 6.8 days to complete one orbit of its star, and it is 0.0653 AU from its host star. [11][12] This and three additional exoplanets; one super-Earth (designated c and later found to be rocky as well), one Neptunian world (d), and one Jovian world (e); were deduced using HARPS-N radial velocity data by Motalebi et al.
