High-precision K2/TESS Photometry and HERMES Spectroscopy of Four Bright Field Stars
Otto Trust, Santosh Joshi, Benard Nsamba +13
Space-based photometry from K2 and TESS, coupled with high-resolution spectroscopy, provides a unique opportunity to re-examine the variability and chemical nature of four bright s…
Revisiting the exoplanet radius valley with host stars from SWEET-Cat
Juma Kamulali, Vardan Adibekyan, Benard Nsamba +7
The radius valley,a deficit of planets near 2 , was observed among exoplanets of radius 5 with periods 100 days by NASA's…
MAISTEP -- a new grid-based machine learning tool for inferring stellar parameters I. Ages of giant-planet host stars
Juma Kamulali, Benard Nsamba, Vardan Adibekyan +3
Our understanding of exoplanet demographics partly depends on their corresponding host star parameters. With the majority of exoplanet-host stars having only atmospheric constraint…
Uniform characterisation of an ensemble of main-sequence benchmark stars: effect of Gaia-based data on grid search models
Benard Nsamba, Achim Weiss, Juma Kamulali
The inference of stellar parameters (such as radius and mass) through asteroseismic forward modelling depends on the number, accuracy, and precision of seismic and atmospheric cons…
On the stellar core physics of the 16 Cyg binary system: constraining the central hydrogen abundance using asteroseismology
Benard Nsamba, Margarida S. Cunha, Catarina I. S. A. Rocha +3
The unprecedented quality of the asteroseismic data of solar-type stars made available by space missions such as NASA's Kepler telescope are making it possible to explore stellar i…
PLATO Hare-and-Hounds exercise: Asteroseismic model fitting of main-sequence solar-like pulsators
M. S. Cunha, I. W. Roxburgh, V. Aguirre Børsen-Koch +19
Asteroseismology is a powerful tool to infer fundamental stellar properties. The use of these asteroseismic-inferred properties in a growing number of astrophysical contexts makes…
