Descripción
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

    CAVITY: Calar Alto Void Integral-field Treasury surveY: I. First public data release
    The Calar Alto Void Integral-field Treasury surveY (CAVITY) is a legacy project aimed at characterising the population of galaxies inhabiting voids, which are the most under-dense regions of the cosmic web, located in the Local Universe. This paper describes the first public data release (DR1) of CAVITY, comprising science-grade optical data cubes

    BOWIE-ALIGN: A JWST comparative survey of aligned versus misaligned hot Jupiters to test the dependence of atmospheric composition on migration history
    A primary objective of exoplanet atmosphere characterization is to learn about planet formation and evolution, however, this is challenged by degeneracies. To determine whether differences in atmospheric composition can be reliably traced to differences in evolution, we are undertaking a transmission spectroscopy survey with JWST to compare the
