Discovery and mass measurement of the hot, transiting, Earth-sized planet GJ 3929 b
J. Kemmer, S. Dreizler, D. Kossakowski +64
We report the discovery of GJ 3929 b, a hot Earth-sized planet orbiting the nearby M3.5 V dwarf star, GJ 3929 (G 180--18, TOI-2013). Joint modelling of photometric observations fro…
A multi-planetary system orbiting the early-M dwarf TOI-1238
E. González-Álvarez, M. R. Zapatero Osorio, J. Sanz-Forcada +53
Two transiting planet candidates with super-Earth radii around the nearby K7--M0 dwarf star TOI-1238 were announced by TESS. We aim to validate their planetary nature using precise…
Weakly Quasisymmetric Near-Axis Solutions to all Orders
Eduardo Rodríguez, Wrick Sengupta, Amitava Bhattacharjee
We show that the equations satisfied by weakly quasisymmetric magnetic fields can be solved to arbitrarily high order in powers of the distance from the magnetic axis. This demonst…
Islands and current singularities in quasisymmetric toroidal plasmas
Eduardo Rodríguez, Amitava Bhattacharjee
The presence of current singularities in a quasisymmetric magnetic field is explored. Quasisymmetry is shown effective in isolating Pfirsch-Schlüter singularities, to leading order…
Luminal Propagation of Gravitational Waves in Scalar-tensor Theories: The Case for Torsion
José Barrientos, Fabrizio Cordonier-Tello, Cristóbal Corral +4
Scalar-tensor gravity theories with a nonminimal Gauss-Bonnet coupling typically lead to an anomalous propagation speed for gravitational waves, and have therefore been tightly con…
Wave Operators, Torsion, and Weitzenböck Identities
José Barrientos, Fernando Izaurieta, Eduardo Rodríguez +1
We offer a mathematical toolkit for the study of waves propagating on a background manifold with nonvanishing torsion. Examples include electromagnetic and gravitational waves on a…
