Asteroseismic ages for 17,000 stars in Kepler, K2 and TESS
Emma Willett, Andrea Miglio, Saniya Khan +9
The availability of asteroseismic constraints for tens of thousands of red giant (RG) stars has opened the door to robust age estimates, enabling time-resolved studies of different…
TOI-283 b: A transiting mini-Neptune in a 17.6-day orbit discovered with TESS and ESPRESSO
F. Murgas, E. Pallé, A. Suárez Mascareño +51
Super-Earths and mini-Neptunes are missing from our Solar System, yet they appear to be the most abundant planetary types in our Galaxy. A detailed characterization of key planets…
A comprehensive study on radial velocity signals using ESPRESSO: Pushing precision to the 10 cm/s level
P. Figueira, J. P. Faria, A. M. Silva +30
We analyse ESPRESSO data for the stars HD10700, HD20794, HD102365, and HD304636 acquired via its Guaranteed Time Observations (GTO) programme. We characterise the stars' radial vel…
Enhanced Mass Loss of Very Massive Stars: Impact on the Evolution, Binary Processes, and Remnant Mass Spectrum
Kendall G. Shepherd, Guglielmo Costa, Cristiano Ugolini +7
Very massive stars (VMS) play a fundamental role in astrophysics due to their winds and supernovae (SN), and their role as massive black hole (BH) progenitors. However, their origi…
DUETS: Setting expectations for asteroseismic binaries and binary products with synthetic populations
A. Mazzi, J. S. Thomsen, A. Miglio +5
Asteroseismology gives us the opportunity to better characterize binaries and their products, and shed light on their role in Galactic populations. We estimate occurrence rates, ma…
