Descripción
Decisive evidence is presented against the validity of the conventional linear decay law for sunspots. Preliminary results from a statistical analysis of Debrecen Photoheliographic Results data show that the decay rate of sunspots is significantly slower in late phases of the decay than in earlier phases. Our findings are compatible with the predictions of a recently developed turbulent erosion model for sunspot decay.

    Study of basaltic asteroids through their phase curves
    Introduction Classified as type-V, the basaltic asteroids of the Main Belt (MB), for the most part, are connected to Vesta's dynamic family. However, since the discovery of the V-type asteroid (1459) Magnya in the outer MB, several new asteroids have been found in different regions, including V-types from inner regions not belonging to the Vesta

    The Gravitational-wave Optical Transient Observer (GOTO)
    The Gravitational-wave Optical Transient Observer (GOTO) is a project dedicated to identifying optical counterparts to gravitational-wave detections using a network of dedicated, wide-field telescopes. After almost a decade of design, construction, and commissioning work, the GOTO network is now fully operational with two antipodal sites: La Palma

    Innovative solution for upgrading commercial bearings for use in cryogenic instruments
    Infrared instruments for astronomy require many bearings for motion that must move in cryogenic conditions. There are poor and expensive options for this, and the companies with qualified bearings only supply after a long time. To attend these constrains, the Instituto de Astrofísica de Canarias (IAC) started to develop a procedure to upgrade
