On the contradictory case of the binary system HD 81809 hosting two pulsating solar-like stars observed by TESS

Maria Pia Di Mauro, Camilla Pezzotti, Nuno Moedas +8

We present a new comprehensive study of HD81809, a nearby binary system of two solar-like stars showing high-amplitude X-ray emission and a well-defined 8-year solar-like magnetic…

Asteroseismic calibration of the Rossby number and its connection to the stellar dynamo and fundamental properties

Alfio Bonanno, Enrico Corsaro, Travis S. Metcalfe +3

The stellar Rossby number, a dimensionless parameter quantifying the influence of Coriolis forces on convective motions, plays a pivotal role in understanding magnetic stellar evol…

Towards a Non-singular Paradigm of Black Hole Physics

Raúl Carballo-Rubio, Francesco Di Filippo, Stefano Liberati +18

The study of regular black holes and black hole mimickers as alternatives to standard black holes has recently gained significant attention, driven both by the need to extend gener…

Tunneling with physics-informed RG flows in the anharmonic oscillator

Alfio Bonanno, Friederike Ihssen, Jan M. Pawlowski

We solve the anharmonic oscillator with physics-informed renormalisation group (PIRG) flows, with an emphasis on the weak coupling regime with its instanton-dominated tunnelling pr…

Magnetic activity evolution of solar-like stars: II. -Ro evolution of Kepler main-sequence targets

Savita Mathur, Angela R. G. Santos, Zachary R. Claytor +16

There is now a large sample of stars observed by the Kepler satellite with measured rotation periods and photometric activity index . We use this data, in conjunction w…
