Pre-nova Observations of T CrB: A view from the CHARA Array
Ryan Norris, Narsireddy Anugu, Thomas Gaudin +38
T CrB is a symbiotic recurrent nova consisting of a red giant and white dwarf with recent eruptions in 1866 and 1946 and an anticipated eruption in the mid 2020s. We report CHARA A…
Quantum vortex driven Kelvin wave in the thermal background of superfluid helium
Simone Scollo, Luca Galantucci, Giorgio Krstulovic
We present numerical evidence that Kelvin waves (KWs) on quantized vortices in superfluid helium can be directly observed in the normal fluid component at finite temperatures. Usin…
Close-in compact super-Earth systems emerging from resonant chains: slow destabilization by unseen remnants of formation
Max Goldberg, Antoine C. Petit
Planet formation simulations consistently predict compact systems of numerous small planets in chains of mean motion resonances formed by planet-disk interaction, but transiting pl…
Diffusion models for polarimetric reconstruction of circumstellar environments
Quentin Villegas, Laurence Denneulin, Simon Prunet +5
In this paper, we propose an approach combining diffusion models and inverse problems for the reconstruction of circumstellar disk images. Our method builds upon the Rhapsodie fram…
Assessing the performance of future space-based detectors: Astrophysical foregrounds and individual sources
Alice Perego, Matteo Bonetti, Alberto Sesana +2
The space mission LISA, scheduled for launch in 2035, aims to detect gravitational wave (GW) signals in the milli-Hz band. In the context of the ESA Voyage 2050 Call for new missio…
Stability of stationary solutions in Acoustic wave turbulence
Guillaume Costa, Giorgio Krstulovic, Sergey Nazarenko
We study the stability of steady-state solutions of the Wave-Kinetic Equations for acoustic waves. Combining theoretical analysis and numerical simulations, we characterise the tim…
