Detailed cool star flare morphology with CHEOPS and TESS

G. Bruno, I. Pagano, G. Scandariato +79

Context. White-light stellar flares are proxies for some of the most energetic types of flares, but their triggering mechanism is still poorly understood. As they are associated wi…

The EBLM Project XI. Mass, radius and effective temperature measurements for 23 M-dwarf companions to solar-type stars observed with CHEOPS

M. I. Swayne, P. F. L. Maxted, A. H. M. J. Triaud +104

Observations of low-mass stars have frequently shown a disagreement between observed stellar radii and radii predicted by theoretical stellar structure models. This ``radius inflat…

Connecting photometric and spectroscopic granulation signals with CHEOPS and ESPRESSO

S. Sulis, M. Lendl, H. Cegla +83

Stellar granulation generates fluctuations in photometric and spectroscopic data whose properties depend on the stellar type, composition, and evolutionary state. In this study, we…

The EBLM project -- IX. Five fully convective M-dwarfs, precisely measured with CHEOPS and TESS light curves

D. Sebastian, M. I. Swayne, P. F. L. Maxted +85

Eclipsing binaries are important benchmark objects to test and calibrate stellar structure and evolution models. This is especially true for binaries with a fully convective M-dwar…

Fundamental effective temperature measurements for eclipsing binary stars -- III. SPIRou near-infrared spectroscopy and CHEOPS photometry of the benchmark G0V star EBLM J0113+31

P. F. L. Maxted, N. J. Miller, S. Hoyer +74

EBLM J0113+31 is moderately bright (V=10.1), metal-poor ([Fe/H]) G0V star with a much fainter M dwarf companion on a wide, eccentric orbit (=14.3 d). We have used near…

The EBLM project -- VIII. First results for M-dwarf mass, radius and effective temperature measurements using CHEOPS light curves

M. I. Swayne, P. F. L. Maxted, A. H. M. J. Triaud +93

The accuracy of theoretical mass, radius and effective temperature values for M-dwarf stars is an active topic of debate. Differences between observed and theoretical values have r…
