Descripción
This paper reports on the fifth STEPHI multi-site photometric campaign in 1993 devoted to the δ Scuti star BDS 1269A (VW Ari). The observation yielded a data set of 150.7 hours. Our analysis has resulted in 7 identified frequencies. These frequencies exhibit three couple-frequency character, and also fit the previous investigations quite well. An attempt to identify the pulsation modes is made, but no equidistant evidence can be detected, and a second-order effect for rotational splitting has to be considered to explain the complicated nature of BDS 1269A.

    A giant planet transiting a 3-Myr protostar with a misaligned disk
    Astronomers have found more than a dozen planets transiting stars that are 10–40 million years old 1, but younger transiting planets have remained elusive. The lack of such discoveries may be because planets have not fully formed at this age or because our view is blocked by the protoplanetary disk. However, we now know that many outer disks are

    WEAVE First Light Observations: Origin and Dynamics of the Shock Front in Stephan's Quintet
    We present a detailed study of the large-scale shock front in Stephan's Quintet, a by-product of past and ongoing interactions. Using integral-field spectroscopy from the new William Herschel Telescope Enhanced Area Velocity Explorer (WEAVE), recent 144 MHz observations from the LOFAR Two-metre Sky Survey, and archival data from the Very Large

    Accurate modeling of the forward-scattering Hanle effect in the chromospheric Ca I 4227 Å line
    Context. Measurable linear scattering polarization signals have been predicted and detected at the solar disk center in the cores of chromospheric lines. These forward-scattering polarization signals, which are of high interest for magnetic field diagnostics, have always been modeled either under the assumption of complete frequency redistribution
