Using HARPS-N to characterise the long-period planets in the PH-2 and Kepler-103 systems
Sophie C. Dubber, Annelies Mortier, Ken Rice +26
We present confirmation of the planetary nature of PH-2b, as well as the first mass estimates for the two planets in the Kepler-103 system. PH-2b and Kepler-103c are both long-peri…
An 11 Earth-Mass, Long-Period Sub-Neptune Orbiting a Sun-like Star
Andrew W. Mayo, Vinesh M. Rajpaul, Lars A. Buchhave +27
Although several thousands of exoplanets have now been detected and characterized, observational biases have led to a paucity of long-period, low-mass exoplanets with measured mass…
Hot, rocky and warm, puffy super-Earths orbiting TOI-402 (HD 15337)
X. Dumusque, O. Turner, C. Dorn +30
TESS is revolutionising the search for planets orbiting bright and nearby stars. In sectors 3 and 4, TESS observed TOI-402 (TIC-120896927), a bright V=9.1 K1 dwarf also known as HD…
K2-291 b: A rocky super-Earth in a 2.2 day orbit
Molly R. Kosiarek, Sarah Blunt, Mercedes Lopez-Morales +43
K2-291 (EPIC 247418783) is a solar-type star with a radius of R_star = 0.899 0.034 R_sun and mass of M_star=0.934 0.038 M_sun. From K2 C13 data, we found one super-Eart…
So close, so different: characterization of the K2-36 planetary system with HARPS-N
M. Damasso, L. Zeng, L. Malavolta +19
K2-36 is a K dwarf orbited by two small ( and ), close-in (=0.022 AU and =0.054 AU) transiti…
HARPS-N radial velocities confirm the low densities of the Kepler-9 planets
L. Borsato, L. Malavolta, G. Piotto +20
We investigated the discrepancy between planetary mass determination using the transit timing variations (TTVs) and radial velocities (RVs), by analysing the multi-planet system Ke…
Masses and radii for the three super-Earths orbiting GJ 9827, and implications for the composition of small exoplanets
K. Rice, L. Malavolta, A. Mayo +34
Super-Earths belong to a class of planet not found in the Solar System, but which appear common in the Galaxy. Given that some super-Earths are rocky, while others retain substanti…
New wavelength calibration of the HARPS spectrograph
Adrien Coffinet, Christophe Lovis, Xavier Dumusque +1
(abridged) Even if the HARPS spectrograph has been operational for more than 15 years and it provides among the most precise Doppler measurements, improvements are still possible.…
