Spectral properties of asteroids in cometary orbits
Aims: In this paper we analyze the spectra of a sample of asteroids in cometary orbits (ACOs) in order to understand the relationship between them, the Jupiter...
Spectral properties of near-Earth objects with low-Jovian Tisserand invariant
The near-Earth objects with low-Jovian Tisserand invariant (T J) represent about 9 per cent of the known objects orbiting in the near-Earth space, being subject...
Spectropolarimetric Evidence for a Siphon Flow along an Emerging Magnetic Flux Tube
We study the dynamics and topology of an emerging magnetic flux concentration using high spatial resolution spectropolarimetric data acquired with the Imaging...
Spectroscopic analysis tool for intEgraL fieLd unIt daTacubEs (SATELLITE): case studies of NGC 7009 and NGC 6778 with MUSE
Integral field spectroscopy (IFS) provides a unique capability to spectroscopically study extended sources over a 2D field of view, but it also requires new...
Spectroscopic and dynamical properties of comet C/2018 F4, likely a true average former member of the Oort cloud
Context. The population of comets hosted by the Oort cloud is heterogeneous. Most studies in this area have focused on highly active objects, those with small...
Spectroscopic characterization of the stellar content of ultra-diffuse galaxies
Understanding the peculiar properties of ultra-diffuse galaxies (UDGs) via spectroscopic analysis is a challenging task requiring very deep observations and...
Spectroscopic hint of a cold stream in the direction of the globular cluster NGC 1851
We present the results of a spectroscopic survey performed in the outskirts of the globular cluster NGC 1851 with VIsible MultiObject Spectrograph (VIMOS)/Very...
Spectroscopic parameters for 451 stars in the HARPS GTO planet search program. Stellar [Fe/H] and the frequency of exo-Neptunes
To understand the formation and evolution of solar-type stars in the solar neighborhood, we need to measure their stellar parameters to high accuracy. We...
