Kepler-10 RV measurements by HARPS-N
Listed in IVOA Registry (Virtual Observatory)
Kepler-10b was the first rocky planet detected by the Kepler satellite and confirmed with radial velocity follow-up observations from Keck-HIRES.
Description
The mass of the planet was measured with a precision of around 30%, which was insufficient to constrain models of its internal structure and composition in detail. In addition to Kepler-10b, a second planet transiting the same star with a period of 45 days was statistically validated, but the radial velocities were only good enough to set an upper limit of 20 M_{Earth}_ for the mass of Kepler-10c.
To improve the precision on the mass for planet b, the HARPS-N Collaboration decided to observe Kepler-10 intensively with the HARPS-N spectrograph on the Telescopio Nazionale Galileo on La Palma. In total, 148 high-quality radial-velocity measurements were obtained over two observing seasons. These new data allow us to improve the precision of the mass determination for Kepler-10b to 15%.

With a mass of 3.33+/-0.49 M_{Earth}_and an updated radius of 1.47_-0.02_^+0.03^ R_{Earth}_, Kepler-10b has a density of 5.8+/-0.8 g/cm3, very close to the value predicted by models with the same internal structure and composition as the Earth. We were also able to determine a mass for the 45-day period planet Kepler-10c, with an even better precision of 11%. With a mass of 17.2+/-1.9 M_{Earth}_ and radius of 2.35_-0.04_^+0.09^ R_{Earth}_, Kepler-10c has a density of 7.1+/-1.0 g/cm3.
Kepler-10c appears to be the first strong evidence of a class of more massive solid planets with longer orbital periods.
