Testing the reliability of magnetic field strength measurements for M dwarfs
I. Amateis, O. Kochukhov, A. Hahlin
M dwarfs host strong magnetic fields that can be measured using several complementary techniques. However, the impact of key methodological choices on Zeeman broadening diagnostics…
VLT/CRIRES+ observations of warm Neptune WASP-107 b: Challenges in detecting molecules with ground-based transmission spectroscopy of cooler and cloudy exoplanets
Linn Boldt-Christmas, Adam D. Rains, Nikolai Piskunov +15
Atmospheres of transiting exoplanets can be studied spectroscopically using space-based or ground-based observations. Each has its own strengths and weaknesses, so there are benefi…
Cloudy with a chance of metals: Indications of CO in the atmosphere of GJ 1214 b from high-resolution K-band spectroscopy
L. Nortmann, D. Cont, F. Lesjak +13
Sub-Neptune exoplanets frequently exhibit muted transmission spectra, with GJ 1214 b being the most prominent example. Following years of intense observing campaigns yielding featu…
Detached eclipsing binary star science in the 2040s
Pierre F. L. Maxted, Dominic M. Bowman, Thomas G. Wilson +7
Detached eclipsing binary stars (DEBS) are currently the best source of accurate and precise fundamental stellar parameters. This makes DEBS crucial targets for constraining the im…
Fundamental effective temperature measurements for eclipsing binary stars - VII. The solar twin in LL Aquarii
N. J. Miller, P. F. L. Maxted, A. Hahlin +1
The eclipsing binary LL Aqr is a bright V = 9.32, detached system consisting of two solar-type stars in an eccentric orbit (P = 20.2 d). The secondary component, LL Aqr B, was prev…
