    Twisting solar coronal jet launched at the boundary of an active region
    Aims: A broad jet was observed in a weak magnetic field area at the edge of active region NOAA 11106 that also produced other nearby recurring and narrow jets...

    Two almost planetary mass survivors of common envelope evolution
    White dwarfs are often found in close binaries with stellar or even substellar companions. It is generally thought that these compact binaries form via common...

    Two black widow pulsars in the optical and X-rays
    Context. Two millisecond pulsars, PSR J1513‑2550 and PSR J2017‑1614, with spin periods of about 2.1 and 2.3 ms were recently discovered in the radio and γ-rays...

    Two Bright M Dwarfs Hosting Ultra-Short-Period Super-Earths with Earth-like Compositions
    We present observations of two bright M dwarfs (TOI-1634 and TOI-1685: J = 9.5-9.6) hosting ultra-short-period (USP) planets identified by the TESS mission. The...

    Two close binaries across the hydrogen-burning limit in the Praesepe open cluster
    We present Keck I/OSIRIS and Keck II/NIRC2 adaptive optics imaging of two member candidates of the Praesepe stellar cluster (d = 186.18 ± 0.11 pc; 590-790 Myr)...

    Two decades of optical timing of the shortest-period binary star system HM Cancri
    The shortest-period binary star system known to date, RX J0806.3+1527 (HM Cancri), has now been observed in the optical for more than two decades. Although it...

    Two distant brown dwarfs in the UKIRT Infrared Deep Sky Survey Deep Extragalactic Survey Data Release 2
    We present the discovery of two brown dwarfs in the UK infrared Telescope (UKIRT) Infrared Deep Sky Survey (UKIDSS) Deep Extragalactic Survey (DXS) Data Release...

    Two Distinct Ancient Components in the Sculptor Dwarf Spheroidal Galaxy: First Results from the Dwarf Abundances and Radial Velocities Team
    We have found evidence for the presence of two distinct ancient stellar components (both >=10 Gyr old) in the Sculptor dwarf spheroidal galaxy. We used the ESO...

    Two emission line objects with z > 0.2 in the optical filament apparently connecting the Seyfert galaxy NGC 7603 to its companion
    We present new spectroscopic observations of an old case of anomalous redshift - NGC 7603 and its companion. The redshifts of the two galaxies which are...
