Detecting Solar-Like Oscillations in the Highest Mass TESS Giants
Noah J. Downing, Madeline Howell, Marc H. Pinsonneault +4
The authors analyze all‑sky TESS data to detect solar‑like oscillations in high‑mass red‑giant stars, identifying 98 oscillating giants (including 43 above 3 M⊙) and revealing a sy…
K 1-6 is a photoionised ISM nebula shaped by a fast-moving hot white dwarf in a triple system
Jaroslav Merc, David Jones, Ana Escorza +22
The study shows that nebula K 1‑6 is not a planetary nebula but interstellar gas photoionised by an evolved hot white dwarf, and that its central star is a hierarchical triple syst…
Hints of enhanced magnetic activity after the intermediate rotation period gap as traced by the chromospheric Ca ii infrared triplet
Diego Godoy-Rivera, Savita Mathur, Tyler Richey-Yowell +5
For low-mass stars (M < 1.4 Msun), the connection between stellar rotation and magnetic activity governs stellar spin-down, shapes the environments of their exoplanets, and provide…
Hidden worlds: a non-transiting candidate planet in the Neptunian desert around the solar-type pulsator KIC 9139163
Sylvain N. Breton, Achrène Dyrek, Carlos Allende Prieto +16
Close-in substellar companions experience strong tidal and magnetic interactions with their host stars and are therefore subject to fast orbital evolution. The solar-type pulsator…
Testing Red Clump Models with the Asteroseismic Binary KIC 10841730
Lea S. Schimak, Timothy R. Bedding, Courtney L. Crawford +9
Binaries in which both stars are pulsating are rare but extremely valuable. We present the first study of an asteroseismic binary system consisting of a core helium-burning red clu…
Peakbagging the K2 KEYSTONE sample with PBjam: characterising the individual mode frequencies in solar-like oscillators
George T. Hookway, Martin B. Nielsen, Guy R. Davies +5
The pattern of individual mode frequencies in solar-like oscillators provides valuable insight into their properties and interior structures. The identification and characterisatio…
