Asteroseismic modelling of solar-type stars: A deeper look at the treatment of initial helium abundance
Benard Nsamba, Nuno Moedas, Tiago L. Campante +7
Detailed understanding of stellar physics is essential towards a robust determination of stellar properties (e.g. radius, mass, and age). Among the vital input physics used in the…
Constraining the oblateness of transiting planets with photometry and spectroscopy
B. Akinsanmi, S. C. C. Barros, N. C. Santos +2
Rapid planetary rotation can cause the equilibrium shape of a planet to be oblate. While planetary oblateness has mostly been probed by examining the subtle ingress and egress feat…
The correlation between photometric variability and radial velocity jitter, based on TESS and HARPS observations
S. Hojjatpanah, M. Oshagh, P. Figueira +9
The current and upcoming high precision photometric surveys such as TESS, CHEOPS, and PLATO will provide the community with thousands of new exoplanet candidates. As a consequence,…
Can planetary rings explain the extremely low density of HIP 41378f?
B. Akinsanmi, N. C. Santos, J. P. Faria +4
The presence of rings around a transiting planet can cause its radius to be overestimated and lead to an underestimation of its density if the mass is known. We employ a Bayesian f…
Can we detect the stellar differential rotation of WASP-7 through theRossiter-McLaughlin observations?
Luisa Maria Serrano, M. Oshagh, H. M. Cegla +4
The Rossiter-McLaughlin (RM) effect is the radial velocity signal generated when an object transits a rotating star. Stars rotate differentially and this affects the shape and ampl…
