HD 119130 b Is Not an "Ultradense" Sub-Neptune
We present a revised mass measurement for HD 119130 b (aka K2-292 b), a transiting planet (P = 17 days, R p = 2.63 ‑ 0.10 + 0.11 R ⊕) orbiting a chromospherically inactive G dwarf, previously thought to be one of the densest sub-Neptunes known. Our follow-up Doppler observations with HARPS, HARPS-N, and HIRES reveal that HD 119130 b is, in fact
