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…
20 years of photometric microlensing events predicted by Gaia DR2: Potential planet-hosting lenses within 100 pc
Alexander J Mustill, Melvyn B Davies, Lennart Lindegren
Context. Gaia DR2 offers unparalleled precision on stars' parallaxes and proper motions. This allows the prediction of microlensing events for which the lens stars (and any planets…
Formation Channels for Blue Straggler Stars
Melvyn B. Davies
In this chapter we consider two formation channels for blue straggler stars: 1) the merger of two single stars via a collision, and 2) those produced via mass transfer within a bin…
The origin of very wide binary stars
M. B. N. Kouwenhoven, S. P. Goodwin, Melvyn B. Davies +3
A large population of fragile, wide (> 1000 AU) binary systems exists in the Galactic field and halo. These wide binary stars cannot be primordial because of the high stellar densi…
Mass transfer in eccentric binaries: the new Oil-on-Water SPH technique
Ross P. Church, Johann Dischler, Melvyn B. Davies +3
To measure the onset of mass transfer in eccentric binaries we have developed a two-phase SPH technique. Mass transfer is important in the evolution of close binaries, and a key is…
