Descripción
In 2010, it was published an analysis of the impact of geological activity on the main astronomical observatories worldwide (Eff-Darwich et al., 2010), among them, Roque de los Muchachos observatory (ORM), in the island of La Palma, Canary Islands (Spain). In this work, we compare the results on geological risk at ORM that were obtained in 2010 with the actual impact of Cumbre Vieja eruption. In this sense, we studied the effects of seismicity, ash fall, landslides and ground deformation at ORM. In general, we found a good agreement between the expected and actual impact of volcanic activity at the observatory; however, large differences were found in the distribution of ash fall, likely due to the improper characterization of the atmospheric inversion layer in the model of the dispersion of the volcanic plume.

    Observational evidence of different formation mechanisms of Solar System-type architectures across spectral types

    Despite being the most abundant classes of known exoplanets, super-Earths and mini-Neptunes are absent in our Solar System, and the exact reason for this is still unknown. Some models suggest that cold-Jupiters play a major role in the formation of inner low-mass planets. This could explain the current architecture of our Solar System, and the

    First light and results for atmospheric characterization with The Near Infra-Red Planet Searcher (NIRPS)

    NIRPS is a new fiber-fed high spectral resolution (~80k) spectrograph assisted by adaptive optics installed on the 3.6m telescope of ESO at LaSilla, Chile. Operated simultaneously with HARPS, NIRPS covers the Y, J, and H bands. The commissioning phase demonstrated high stability for time-series observations along precise radial velocities reaching

    3.5 years of observing exoplanet day sides with CHEOPS

    Characterising Exoplanets Satellite (CHEOPS) is the first ESA exoplanet space mission. The satellite carries a 30cm telescope, optimised to deliver exquisite (ppm-level) photometry of bright exoplanetary systems at optical wavelengths. CHEOPS has spent approximately 20% of its observing time during its 3.5-year long nominal mission studying
