The conformal limit for bimerons in easy-plane chiral magnets
We study minimizers $\boldsymbol{m}\colon \mathbb R^2\to\mathbb S^2$ of the energy functional \begin{align*} E_σ(\boldsymbol{m}) = \int_{\mathbb R^2} \bigg(\frac 12 |\nabla\boldsymbol{m}|^2 +σ^2 \boldsymbol{ m} \cdot \nabla \times\boldsymbol{m} +σ^2 m_3^2 \bigg)\, dx\,, \end{align*} for $0<σ\ll 1$, with prescribed topological degree \begin{align*} Q(\boldsymbol{m})=\frac{1}{4π} \int_{\mathbb R^2}\boldsymbol{m} \cdot \partial_1 \boldsymbol{m}\times\partial_2\boldsymbol{m}\, dx =…

A circularly polarized low-frequency radio burst from the exoplanetary system HD 189733
We aim to detect low-frequency radio emission from exoplanetary systems, which can provide insights into planetary magnetic fields, star-planet interactions, stellar activity, and exo-space weather. The HD 189733 system, hosting a well-studied hot Jupiter, is a prime target for such searches. We conducted NenuFAR imaging observations in the 15-62 MHz range, in order to cover the entire orbital phase of HD 189733 b. Dynamic spectra were generated for the target and other sources in the field, fo…
