Description
We report on the serendipitous discovery of a Herbig-Haro flow close to the pre-main sequence system HV Tauri. Low resolution spectra indicate a high excitation flow. The profile of emission lines seen at high resolution shows the existence of two velocity components, which are interpreted as emission from a bow shock directed towards the observer, moving with a velocity of about 300 km/s at an angle of 60 deg to the line of sight. We argue that the most likely source of the flow is HV Tau AB, which would be the first known case of a weak T Tauri star driving a Herbig-Haro flow.

    An ultra-short-period super-Earth with an extremely high density and an outer companion
    We present the discovery and characterization of a new multi-planetary system around the Sun-like star K2-360 (EPIC 201595106). K2-360 was first identified in K2 photometry as the host of an ultra-short-period (USP) planet candidate with a period of 0.88 d. We obtained follow-up transit photometry, confirming the star as the host of the signal

    High-resolution observations of recurrent jets from an arch filament system
    Context. Solar jets are collimated plasma ejections along magnetic field lines observed in hot (extreme-ultraviolet (EUV) jets) and cool (chromospheric surges) temperature diagnostics. Their trigger mechanisms and the relationship between hot and cool jets are still not completely understood. Aims. We aim to investigate the generation of a sequence

    KISS: Instrument Description and Performance
    Kinetic inductance detectors (KIDs) have been proven as reliable systems for astrophysical observations, especially in the millimeter range. Their compact size enables them to optimally fill the focal plane, thus boosting sensitivity. The KIDs Interferometric Spectral Surveyor (KISS) instrument is a millimeter camera that consists of two KID arrays
