Ultracompact binary systems, consisting of two compact objects in an orbit $\lesssim 0.5 {\rm R}_\odot$, should exhibit measurable rates of orbital period change ( $\dot{P} \ne 0$) due to the emission of gravitational waves (GWs). Measurements of $\dot{P}$ have so far been limited to the shortest-period ultracompact binaries ( $\lesssim 20$ min)

Context. Milky Way analogs (MWAs) are defined on the basis of structural, kinematic, and global physical parameters. Our advanced approach to searching for MWAs also includes principal features of the Milky Way (MW) such as its isolated position in the local cosmic web, absent or weak nuclear activity, and the low mass of the supermassive black

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

Context. Interior models predict that stellar envelopes change from convective to radiative during the pre-main-sequence (pre-MS) evolution of intermediate-mass stars. Although the amount of surface lithium (Li) is a direct probe of mixing in stellar interiors, analyses focused on this type of source are practically absent. Aims. We contribute to

We present 5 GHz e-MERLIN radio images at 50 mas resolution of the nuclear regions of the Legacy e-MERLIN Multi-band Imaging of Nearby Galaxies survey (LeMMINGs): the deepest statistically complete radio-band survey of the local Universe ( $\lt$120 Mpc), consisting of 280 galaxies spanning all morphological and nuclear types. We detect nuclear

We present the combined JWST/NIRSpec/G395H and NIRISS/SOSS transmission spectrum of a warm mini-Neptune, TOI-1130 b (3.66 R ⊕, 19.8 M ⊕, and T eq ∼ 825 K). It is part of a rare and unique multiplanet system, TOI-1130, which hosts an inner mini-Neptune and an outer hot Jupiter locked in a 2:1 mean motion resonance. From the transmission spectrum of
