Quantifying isochrone-based age uncertainties for rapidly rotating A-type stars
Simon J. Murphy, Anuj Gautam, Zachary R. Claytor
Accurate stellar ages and masses are essential for interpreting the demographics and physical properties of exoplanets, particularly for intermediate-mass, early-type stars where c…
Variability classification of TESS targets in LOPS2, the first long-term pointing field of PLATO. Version 1 of the public variability catalogue
Mykyta Kliapets, Pablo Huijse, Jeroen Audenaert +28
The PLAnetary Transits and Oscillations of stars (PLATO) mission is expected to launch in January 2027. A total of 8\% of its data rate will be dedicated to complementary science t…
FQ Circini: An Ordinary Nova with a High-mass B1 V(n)(e) Companion Whose Decretion Disk Transfers Mass to the White Dwarf via Roche-Lobe Overflow
Bradley E. Schaefer, Andrew Pearce, Tom Love +4
FQ Cir was an ordinary fast He/N classical nova, peaking at =10.9. The pre-eruption and post-eruption counterpart was at =14.0, making the smallest known classical nova ampli…
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…
Asteroseismic detection of a predominantly toroidal magnetic field in the deep interior of the main-sequence F star KIC 9244992
Masao Takata, Simon J. Murphy, Donald W. Kurtz +2
An asteroseismic analysis has revealed a magnetic field in the deep interior of a slowly-rotating main-sequence F star KIC9244992, which was observed by the Kepler spacecraft for f…
The Age and High Energy Environment of the Very Young Transiting Exoplanet TOI 1227b
Attila Varga, Joel H. Kastner, Alexander S. Binks +2
The mid-M star TOI~1227 hosts among the youngest known transiting exoplanets. We have conducted new X-ray imaging and optical spectroscopic observations of TOI 1227 aimed at ascert…
