Chemical paradox in a binary system: Exploring metal enrichment in HD 81809B
Nuno Moedas, Maria Pia Di Mauro
The HD 81809 system presents peculiar chemical composition with a large metallicity difference between its two components: the primary has low metallicity ([Fe/H]=-0.57 dex), while…
Ariel stellar characterisation IV. Fundamental parameters of 18 hot stars in the Ariel mission candidate sample
H. Ramler, S. P. D. Borthakur, C. P. Folsom +16
The characterisation of exoplanetary systems depends on the accurate determination of host star parameters. The Ariel mission will probe the atmospheres of a statistically signific…
On the contradictory case of the binary system HD 81809 hosting two pulsating solar-like stars observed by TESS
Maria Pia Di Mauro, Camilla Pezzotti, Nuno Moedas +8
We present a new comprehensive study of HD81809, a nearby binary system of two solar-like stars showing high-amplitude X-ray emission and a well-defined 8-year solar-like magnetic…
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…
Studying the surface effect in Procyon A as an F-type star
Nuno Moedas, Maria Pia Di Mauro
Procyon A is an F-type main-sequence star in a binary system. It has been the subject of numerous ground-based and space-based observing campaigns, providing precise classical cons…
