dc.description.abstract | HD 3167 is a bright (V = 8.9), nearby K0 star observed by the NASA K2 mission (EPIC 220383386), hosting two small, short-period transiting planets. Here we present the results of a multi-site, multi-instrument radial-velocity campaign to characterize the HD 3167 system. The masses of the transiting planets are 5.02 ± 0.38 {M}<SUB>\oplus </SUB> for HD 3167 b, a hot super-Earth with a likely rocky composition ({ρ }<SUB>b</SUB> = {5.60}<SUB>-1.43</SUB><SUP>+2.15</SUP> g cm<SUP>-3</SUP>), and {9.80}<SUB>-1.24</SUB><SUP>+1.30</SUP> {M}<SUB>\oplus </SUB> for HD 3167 c, a warm sub-Neptune with a likely substantial volatile complement ({ρ }<SUB>c</SUB> = {1.97}<SUB>-0.59</SUB><SUP>+0.94</SUP> g cm<SUP>-3</SUP>). We explore the possibility of atmospheric composition analysis and determine that planet c is amenable to transmission spectroscopy measurements, and planet b is a potential thermal emission target. We detect a third, non-transiting planet, HD 3167 d, with a period of 8.509 ± 0.045 d (between planets b and c) and a minimum mass of 6.90 ± 0.71 {M}<SUB>\oplus </SUB>. We are able to constrain the mutual inclination of planet d with planets b and c: we rule out mutual inclinations below 1.°3 because we do not observe transits of planet d. From 1.°3 to 40°, there are viewing geometries invoking special nodal configurations, which result in planet d not transiting some fraction of the time. From 40° to 60°, Kozai-Lidov oscillations increase the system’s instability, but it can remain stable for up to 100 Myr. Above 60°, the system is unstable. HD 3167 promises to be a fruitful system for further study and a preview of the many exciting systems expected from the upcoming NASA TESS mission. | en_US |
