An Improved Transit Measurement for a 2.4[subscript ⊕] Planet Orbiting A Bright Mid-M Dwarf K2–28
We present a new Spitzer transit observation of K2-28b, a sub-Neptune (R[subscript p] = 2.45 ± 0.28 R[subscript ⊕]) orbiting a relatively bright (V[subscript mag] = 16.06, K[subscript mag] = 10.75) metal-rich M4 dwarf (EPIC 206318379). This star is one of only seven with masses less than 0.2 known t...
