EPRV Asteroseismology of the K dwarfs GJ 570 A and GJ 783 A with ESPRESSO. Empirical mode-amplitude scaling in tension with 3D convection simulations

T. L. Campante, Y. Zhou, Y. Li +21

Solar-like oscillations in K dwarfs have intrinsically low amplitudes, making them challenging to detect in space-based photometry. The advent of Extremely Precise Radial Velocity…

Asteroseismic investigation of HD 140283: The Methuselah star

M. S. Lundkvist, J. R. Larsen, Y. Li +12

HD 140283 is a well-studied metal-poor subgiant and a Gaia benchmark star, often used for testing stellar models due to its proximity, brightness, and low metallicity ([Fe/H] = -2.…

Constraining nearby substellar companion architectures using High Contrast Imaging, Radial Velocity and Astrometry data

L. F. Sartori, M. J. Bonse, Y. Li +3

Nearby stars offer prime opportunities for exoplanet discovery and characterization through various detection methods. By combining HCI, RV, and astrometry, it is possible to bette…

Two successive EUV waves and a transverse oscillation of a quiescent prominence

Q. M. Zhang, M. S. Lin, X. L. Yan +4

In this paper, we carry out multiwavelength observations of two successive extreme-ultraviolet (EUV) waves originating from active region (AR) NOAA 13575 and a transverse oscillati…

Expanding the frontiers of cool-dwarf asteroseismology with ESPRESSO. Detection of solar-like oscillations in the K5 dwarf Indi

T. L. Campante, H. Kjeldsen, Y. Li +25

Fuelled by space photometry, asteroseismology is vastly benefitting the study of cool main-sequence stars, which exhibit convection-driven solar-like oscillations. Even so, the tin…

Shell helium-burning hot subdwarf B stars as candidates for blue large-amplitude pulsators

H. Xiong, L. Casagrande, X. Chen +7

Blue large-amplitude pulsators (BLAPs) are a newly discovered type of variable star. Their typical pulsation periods are on the order of a few tens of minutes, with relatively larg…

The long-lasting activity of 3C 454.3. GASP-WEBT and satellite observations in 2008-2010

C. M. Raiteri, M. Villata, M. F. Aller +6

We present multiwavelength observations of 3C 454.3 from April 2008 to March 2010. The radio to optical data are mostly from the GASP-WEBT, UV and X-ray data from Swift, and gamma-…
