TOI-1438: A rare system with two short-period sub-Neptunes and a tentative long-period Jupiter-like planet orbiting a K0V star

Carina M. Persson, Emil Knudstrup, Ilaria Carleo +44

We present the detection and characterisation of the TOI-1438 multi-planet system discovered by TESS. We collected a series of follow-up observations including high-spectral resolu…

Beyond the Nyquist frequency: Asteroseismic catalog of undersampled Kepler late subgiants and early red giants

B. Liagre, R. A. García, S. Mathur +9

Subgiants and early red giants are crucial for studying the first dredge-up, a key evolutionary phase where the convective envelope deepens, mixing previously interior-processed ma…

Rotation of young solar-type stars as seen by Gaia and K2

Sylvain N. Breton, Elisa Distefano, Alessandro C. Lanzafame +1

Accurate surface rotation measurements are crucial to estimate stellar ages and improve our understanding of stellar rotational evolution. Comparisons of datasets obtained from dif…

Precise Asteroseismic Ages for the Helmi Streams

Christopher J. Lindsay, Marc Hon, J. M. Joel Ong +6

The Helmi streams are remnants of a dwarf galaxy that was accreted by the Milky Way and whose stars now form a distinct kinematic and chemical substructure in the Galactic halo. Pr…

Magnetic activity evolution of solar-like stars: II. -Ro evolution of Kepler main-sequence targets

Savita Mathur, Angela R. G. Santos, Zachary R. Claytor +16

There is now a large sample of stars observed by the Kepler satellite with measured rotation periods and photometric activity index . We use this data, in conjunction w…
