Descripción
The population of black widows, binary systems containing a millisecond pulsar and a very low-mass companion star exposed to the high-energy pulsar wind, has grown exponentially in the past few years. The number of black widow candidates is now over 30 systems, but only 14 have been confirmed so far. Their relevance in analysing the extremes of the neutron stars properties led to multiwavelength dedicated studies that revealed a rich phenomenology. In this work, we provide a glimpse into the black widow class through modelling of high-cadence multi-band light curves of 6 systems, accounting for almost half of the confirmed population. A better understanding of the black widow population, which hosts some of the most massive and fastest spinning neutron stars, will ultimately benefit future modelling of compact object mergers.

    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
