Exploring the ultrahot Neptune LTT 9779 b with CRIRES+. Non-detection of helium transmission spectra and detection of HO on the dayside

S. Liu, F. Yan, L. Nortmann +15

Ultrahot Neptunes reside in the most extreme irradiation regime of the hot Neptune desert and remain challenging targets for atmospheric characterization because of their low plane…

Unlocking new information in stellar circular polarisation with second-order least-squares deconvolution

Oleg Kochukhov

Least-squares deconvolution (LSD) is the standard technique for measuring stellar magnetic fields from circular polarisation spectra. It rests on the weak-field approximation and y…

Evidence for the emergence of stellar magnetic fields during rapid mass transfer

Gregg A. Wade, Tomer Shenar, Pablo Marchant +6

Binary interaction fundamentally alters the evolution of massive stars, yet the physical consequences of mass transfer remain poorly constrained. Here we present high-resolution sp…

Stellar masses and ages in Gaia Data Release 4 from the Final Luminosity Age Mass Estimator algorithm

Orlagh L. Creevey, Laia Casamiquela, Yveline Lebreton +23

The masses and ages of stars are key quantities for understanding exoplanetary, stellar, and galactic evolution. In the context of Gaia, these parameters provide insights into the…

Using ZDI maps to determine magnetic forces and torques at the photospheres of Early-type stars

James MacDonald, Tali Natan, Véronique Petit +2

We use the magnetic field components measured by Zeeman Doppler imaging (ZDI) to calculate the stellar surface force and torque due to magnetic stresses for the fast rotators O…

TESS Cycle 2 observations of roAp stars with 2-min cadence data

D. L. Holdsworth, M. S. Cunha, M. Lares-Martiz +46

We present the results of a systematic search of the Transiting Exoplanet Survey Satellite (TESS) 2-min cadence data for new rapidly oscillating Ap (roAp) stars observed during the…
