Continuous Wide-Field Optical Monitoring for Very Early-Phase Transient Discovery

M. Della Valle, Maria Teresa Botticella, Enrico Cappellaro, Roberto Ragazzoni et autres

The study of transient phenomena in a multimessenger context is expected to remain a major pillar of astrophysical discovery in the decades ahead. Supernovae, Kilonovae, Black-Hole formation, Novae, GRBs, and tidal disruption events are prime examples, as their earliest phases link electromagnetic …

The Gaia-ESO Survey: projected rotational velocities of B stars in the Carina Nebula

S. Daflon, J. V. Sales Silva, Kátia Almeida Cunha, Ronny M. Blomme et autres

ABSTRACT The Carina Nebula is an active star-forming region with several open clusters rich in massive OB stars, thus making it an optimal target for studying stellar properties such as rotation for large samples of these early-type stars. We studied a sample …

Characterization of a Fragmentation in a Highly Elliptical Orbit via an Optical Multi-Observatory Survey Strategy

Matteo Rossetti, Lorenzo Cimino, Lorenzo Mariani, Simone Varanese et autres

Surveys of fragmentations, especially in the early stages of the given event, are fundamental for determining the number of fragments, identifying and cataloging them, and monitoring their future evolution. The development of a ground-based optical survey strategy, i.e., a suitable observation and …

Evolutionary tracks, ejecta, and ionizing photons from intermediate-mass to very massive stars with PARSEC

Guglielmo Costa, Kendall Shepherd, A. Bressan, Francesco Addari et autres

Recent advancements in stellar evolution modeling offer unprecedented accuracy in predicting the evolution and deaths of stars. We present new stellar evolutionary models computed with the updated PARSEC V2.0 code for a comprehensive and homogeneous grid of metallicities and initial masses. Nuclear …

Thermo-mechanical sizing and stress-induced birefringence analysis for the MezzoCielo assembly

Silvio Di Rosa, Roberto Ragazzoni, Marco Dima, Luigi Lessio et autres

MezzoCielo telescope aims to be a revolutionary optical instrument, designed to exhibit a field of view of around 104 square degrees. As such, it will be able to carry out whole-sky patrolling, which could be exploited, for instance, to track space debris …

FlyEye Ground-Based Telescope: Unveiling New Frontiers in Astronomical Science

Carmelo Arcidiacono, Matteo Simioni, Roberto Ragazzoni, Piero Gregori et autres

The FlyEye design makes its debut in the ESA's NEOSTEL developed by OHB-Italia. This pioneering FlyEye telescope integrates a monolithic 1-meter class primary mirror feeding 16 CCD cameras for discovering Near-Earth Object (NEO) and any class of transient phenomena. OHB-Italia is the …

Engineering a whole sky one meter class telescope: MezzoCielo as a patrol of transients

Roberto Ragazzoni, Silvio Di Rosa, P. Spanò, Demetrio Magrin et autres

MezzoCielo is a project of a monocentric optical system with a spherical glass envelope built up by meniscus arranged onto a Platonic or Fullerene-like structure filled with industrial liquid characterized by high transparency and low refractive index. Optical design of the cameras, …
