Description
High-speed photometric observations were performed of the Ap stars HD62140 (49 Cam), HD81009, and HD22374 for more than 60 hr in Oct. and Dec. 1986. Photometric measurements in the B band were reduced and the residuals obtained were subjected to a harmonic analysis, searching for periodicities in the range of a few minutes to 2 hr. There is evidence that the star 49 Cam is oscillating; HD81009 and HD22374 were observed in order to confirm traces of oscillation present in earlier observations, however, these possible oscillations did not repeat in the new data.

    MAAT: an IFU for GTC optimized using spectrograph wavefront measurements and superoptimization
    The Mirror-slicer Array for Astronomical Transients (MAAT) is an IFU now being manufactured for the OSIRIS spectrograph on the 10.4-m GRANTECAN (GTC) telescope at La Palma. It is based on the Advanced Image Slicer (AIS) concept as are MUSE and KMOS on the VLT (among many others). Very significant changes to the design had to be made due in part to

    JWST observations of Chiron: A unique active Centaur beyond 18 AU
    Chiron is the second-largest Centaur, with an effective diameter of 210 km, and is among the most well-studied minor bodies in the middle and outer Solar System. Notably, Chiron belongs to the enigmatic subpopulation of active Centaurs and has displayed cometary activity several times since its discovery. In March 2021, Chiron underwent an outburst

    FRIDA: diffraction-limited imaging and integral-field spectroscopy for the GTC
    FRIDA is a diffraction-limited imager and integral-field spectrograph for the adaptive-optics focus of the Gran Telescopio Canarias. In imaging mode FRIDA provides scales of 10, 20 and 40 mas/pixel and in IFS mode spectral resolutions of about 1200, 4000 and 30,000. Coronographic masks are available in both modes for highcontrast images. FRIDA is
