Kepler-11 is a Solar Twin: Revising the Masses and Radii of Benchmark Planets Via Precise Stellar Characterization
Megan Bedell, Jacob L. Bean, Jorge Melendez +7
The six planets of the Kepler-11 system are the archetypal example of a population of surprisingly low-density transiting planets revealed by the Kepler mission. We have determined…
The Solar Twin Planet Search. V. Close-in, low-mass planet candidates and evidence of planet accretion in the solar twin HIP 68468
Jorge Melendez, Megan Bedell, Jacob L. Bean +14
[Methods]. We obtained high-precision radial velocities with HARPS on the ESO 3.6 m telescope and determined precise stellar elemental abundances (~0.01 dex) using MIKE spectra on…
K2-98 b: A 32-M Neptune-sized planet in a 10-day orbit transiting an F8 star
Oscar Barragán, Sascha Grziwa, Davide Gandolfi +21
We report the discovery of K2-98 b (EPIC 211391664 b), a transiting Neptune-sized planet monitored by the K2 mission during its campaign 5. We combine the K2 time-series data with…
The Solar Twin Planet Search: IV. The Sun as a typical rotator and evidence for a new rotational braking law for Sun-like stars
Leonardo A. dos Santos, Jorge Meléndez, José-Dias do Nascimento +8
It is still unclear how common the Sun is when compared to other similar stars in regards to some of its physical properties, such as rotation. Considering that gyrochronology rela…
HELIOS: An Open-source, GPU-accelerated Radiative Transfer Code For Self-consistent Exoplanetary Atmospheres
Matej Malik, Luc Grosheintz, João M. Mendonça +10
We present the open-source radiative transfer code named HELIOS, which is constructed for studying exoplanetary atmospheres. In its initial version, the model atmospheres of HELIOS…
The Solar Twin Planet Search III. The [Y/Mg] clock: estimating stellar ages of solar-type stars
M. Tucci Maia, I. Ramírez, J. Meléndez +3
Solar twins are stars with similar stellar (surface) parameters to the Sun that can have a wide range of ages. This provide an opportunity to analyze the variation of their chemica…
