Stellar spectral-type (mass) dependence of the dearth of close-in planets around fast-rotating stars. Architecture of Kepler confirmed single-exoplanet systems compared to star-planet evolution models
R. A. García, C. Gourvès, A. R. G. Santos +8
In 2013 a dearth of close-in planets around fast-rotating host stars was found using statistical tests on Kepler data. The addition of more Kepler and Transiting Exoplanet Survey S…
Asteroseismology and Spectropolarimetry of the Exoplanet Host Star Serpentis
Travis S. Metcalfe, Derek Buzasi, Daniel Huber +31
The bright star Ser hosts a hot Neptune with a minimum mass of 13.6 and a 15.5 day orbit. It also appears to be a solar analog, with a mean rotation period of 25.8 d…
Asteroseismology with the Roman Galactic Bulge Time-Domain Survey
Daniel Huber, Marc Pinsonneault, Paul Beck +24
Asteroseismology has transformed stellar astrophysics. Red giant asteroseismology is a prime example, with oscillation periods and amplitudes that are readily detectable with time-…
Magnetic activity evolution of solar-like stars: I. S_ph-Age relation derived from Kepler observations
Savita Mathur, Zachary R. Claytor, Angela R. G. Santos +9
The ages of solar-like stars have been at the center of many studies such as exoplanet characterization or Galactic-archaeology. While ages are usually computed from stellar evolut…
Temporal variation of the photometric magnetic activity for the Sun and Kepler solar-like stars
A. R. G. Santos, S. Mathur, R. A. García +9
The photometric time series of solar-like stars can exhibit rotational modulation due to active regions co-rotating with the stellar surface, allowing us to constrain stellar rotat…

Tiago L. Campante, Tanda Li, J. M. Joel Ong +23
Asteroseismology is playing an increasingly important role in the characterization of red-giant host stars and their planetary systems. Here, we conduct detailed asteroseismic mode…
Multi-campaign Asteroseismic Analysis of eight Solar-like pulsating stars observed by the K2 mission
L. González-Cuesta, S. Mathur, R. A. García +11
The NASA K2 mission that succeeded the nominal Kepler mission observed several hundreds of thousands of stars during its operations. While most of the stars were observed in single…
TESS Asteroseismic Analysis of HD 76920: The Giant Star Hosting An Extremely Eccentric Exoplanet
Chen Jiang, Tao Wu, Adina D. Feinstein +30
The Transiting Exoplanet Survey Satellite (TESS) mission searches for new exoplanets. The observing strategy of TESS results in high-precision photometry of millions of stars acros…
Stochastic excitation of internal gravity waves in rotating late F-type stars: A 3D simulation approach
Sylvain N. Breton, Allan Sacha Brun, Rafael A. García
There are no strong constraints placed thus far on the amplitude of internal gravity waves (IGWs) that are stochastically excited in the radiative interiors of solar-type stars. La…
Hunting for anti-solar differentially rotating stars using the Rossby number -- An application to the Kepler field
Quentin Noraz, Sylvain N. Breton, Allan Sacha Brun +5
Anti-solar differential rotation profiles have been found for decades in numerical simulations of convective envelopes of solar-type stars. These profiles are characterized by a sl…
Spinning up the Surface: Evidence for Planetary Engulfment or Unexpected Angular Momentum Transport?
Jamie Tayar, Facundo D. Moyano, Melinda Soares-Furtado +15
In this paper, we report the potential detection of a nonmonotonic radial rotation profile in a low-mass lower-luminosity giant star. For most low- and intermediate-mass stars, the…
Deciphering stellar chorus: apollinaire, a Python 3 module for Bayesian peakbagging in helio- and asteroseismology
S. N. Breton, R. A. García, J. Ballot +2
Since the asteroseismic revolution, availability of efficient and reliable methods to extract stellar-oscillation mode parameters has been one of the keystone of modern stellar phy…
K2-99 revisited: a non-inflated warm Jupiter, and a temperate giant planet on a 522-d orbit around a subgiant
A. M. S. Smith, S. N. Breton, Sz. Csizmadia +29
We report new photometric and spectroscopic observations of the K2-99 planetary system. Asteroseismic analysis of the short-cadence light curve from K2's Campaign 17 allows us to r…
No swan song for Sun-as-a-star helioseismology: performances of the Solar-SONG prototype for individual mode characterisation
S. N. Breton, P. L. Pallé, R. A. García +5
The GOLF instrument on board SoHO has been in operation for almost 25 years but aging of the instrument has now strongly affected its performance, especially in the low-frequency p…
