In a magnetically dominated model of star formation, we expect to see alignments between the magnetic field orientation of star-forming dense cores and the cloud-scale magnetic field. A. Pandhi et al. showed instead, however, that the orientation of cores and their angular momentum vectors appear random with respect to the larger-scale magnetic

Young exoplanets provide vital insights into the early dynamical and atmospheric evolution of planetary systems. Many multi-planet systems younger than 100 Myr exhibit mean-motion resonances, probably established through convergent disk migration. Over time, however, these resonant chains are often disrupted, mirroring the Nice model proposed for

We report a mm-wave search for axion dark matter from SGR 1745─2900, based on 4.8 h of ALMA observations. No candidate features are found between 133.99─135.78, 135.91─137.70, 145.99─147.78, and 147.99─149.78 GHz, corresponding to 0.55─0.62 meV. Interpreting this null result within a state-of-the-art stellar framework, we derive sensitivity to the
