Spot-Crossing Variations Confirm a Misaligned Orbit for a Planet Transiting an M Dwarf

Posted by dbos June 13, 2025MIT

Kavli Affiliate: Avi Shporer | First 5 Authors: Patrick Tamburo, Samuel W. Yee, Juliana García-Mejía, David Charbonneau, Allyson Bieryla | Summary: TOI-3884~b is an unusual 6.4~R$_oplus$ planet orbiting an M4 host, whose transits display large and persistent spot-crossing events. We used the textit{Tierras} Observatory to monitor both the long-term photometric variability of TOI-3884 and changes […]

Credit Assignment via Behavioral Timescale Synaptic Plasticity: Theoretical Frameworks

Posted by dbos June 13, 2025June 23, 2025Columbia

Kavli Affiliate: Rui Costa | Authors: Ian Cone, Claudia Clopath and Rui Ponte Costa | Summary: Behavioral Timescale Synaptic Plasticity (BTSP) is a form of synaptic plasticity in which dendritic Ca2+ plateau potentials in hippocampal pyramidal neurons drive rapid place field formation. Unlike traditional learning rules, BTSP learns correlations on the timescales of seconds and […]

Magnon-magnon interaction induced by nonlinear spin wave dynamics

Posted by klaurent June 13, 2025Delft

Kavli Affiliate: Herre S. J. Van Der Zant | First 5 Authors: Matteo Arfini, Matteo Arfini, , , | Summary: We experimentally and theoretically demonstrate that nonlinear spin-wave dynamics can induce an effective resonant interaction between non-resonant magnon modes in a yttrium iron garnet disk. Under strong pumping near the ferromagnetic resonance mode, we observe […]
