On may 16, 2019 the transiting exoplanet survey satellite (tess) discovered two exoplanets orbiting a nearby sun-like star, hd 15337, with mass ma = 0.90m⊙. we will focus on the information that led to the discovery of the further of the two planets. the time between transits is p = 17.2 days. during a transit, the time from first to second contact is t2 − t1 = 6.4 minutes and the time from first to third contact ist3 − t1 = 111 minutes. doing follow-up radial velocity measurements of the star, you find that the peak radial velocity is vr = 3.798 km/s.
a. what is the semi-major axis of the planet’s orbit in au? b. what is the radius of the planet in earth radii?
c. what is the mass of the planet in earth masses?
