Characterising the interior of five inner Saturnian moons using Cassini ISS data
Lainey, V.; Rambaux, N.; Zhang, Q. +2 more
Context. The Cassini-Huygens space mission provided a huge amount of data for the Saturnian system. While the mission ended in September 2017, there is still much information to be retrieved from the data.
Aims: Here, from their orbital motion, we infer the interior of the five inner Saturnian moons, Atlas, Prometheus, Pandora, Janus, and Epi…
L 363-38 b: A planet newly discovered with ESPRESSO orbiting a nearby M dwarf star
Sartori, Lia F.; Lendl, Monika; Cugno, Gabriele +7 more
Context. Planets around stars in the solar neighbourhood will be prime targets for characterisation with upcoming large space- and ground-based facilities. Since large-scale exoplanet searches will not be feasible with such telescopes, it is crucial to use currently available data and instruments to find possible target planets before next-generat…
VISIONS: the VISTA Star Formation Atlas. II. The data processing pipeline
Meingast, Stefan; Rottensteiner, Alena; Bouy, Hervé +3 more
The VISIONS public survey provides large-scale, multi-epoch imaging of five nearby star-forming regions at sub-arcsecond resolution in the near-infrared. All data collected within the program and provided by the European Southern Observatory (ESO) science archive are processed with a custom end-to-end pipeline infrastructure to provide science-rea…
Investigating the vertical distribution of the disk as a function of radial action
Zhao, Gang; Chen, Yuqin; Du, Cuihua +1 more
Aims: As heating processes can broaden the distributions of radial actions and the vertical distributions of the Galactic disks, we investigate the vertical distribution of the Galactic disks as a function of radial action based on Apache Point Observatory Galactic Evolution Experiment (APOGEE) and Gaia data in order to deepen our understandi…
New members of the Lupus I cloud based on Gaia astrometry. Physical and accretion properties from X-shooter spectra
Bayo, A.; Alcalá, J. M.; Montalto, M. +13 more
We characterize twelve young stellar objects (YSOs) located in the Lupus I region, spatially overlapping with the Upper Centaurus Lupus (UCL) sub-stellar association. The aim of this study is to understand whether the Lupus I cloud has more members than what has been claimed so far in the literature and gain a deeper insight into the global proper…
A multifrequency characterization of the extragalactic hard X-ray sky. Presenting the second release of the Turin-SyCAT
Masetti, N.; Chavushyan, V.; Bottacini, E. +5 more
Context. Nowadays, we know that the origin of the cosmic X-ray background (CXB) is mainly due to the integrated emission of active galactic nuclei. Therefore, in order to obtain a precise estimate of the contribution of different source classes to the CXB, it is crucial to achieve full characterization of the hard-X ray sky.
Aims: We present …
Analysis of minimum ionising particles and soft protons using XMM-Newton EPIC pn-CCD as a particle detector
Freyberg, M. J.; Kirsch, M. G. F.; Bender, V. +1 more
Context. Spacecrafts with imaging telescopes often carry a charge-coupled device (CCD) in their focal plane to detect electromagnetic radiation. Charged particles such as electrons, protons, and heavy ions can reach the CCD and deposit their energy in the detector material. To counteract this undesirable effect, algorithms are usually implemented …
The kinematics of the magnetized protostellar core IRAS15398-3359
Caselli, Paola; Redaelli, Elena; Tabatabaei, Farideh S. +1 more
Context. Observations of protostellar envelopes are essential in order to understand better the process of gravitational collapse toward star and planet formation. From a theoretical perspective, magnetic fields are considered an important factor during the early stages of star formation, especially during the main accretion phase.
Aims: Our …
The equilibrium shape of (65) Cybele: primordial or relic of a large impact?
Jorda, L.; Carry, B.; Molina, D. +24 more
Context. Cybele asteroids constitute an appealing reservoir of primitive material genetically linked to the outer Solar System, and the physical properties (size and shape) of the largest members can be readily accessed by large (8m class) telescopes.
Aims: We took advantage of the bright apparition of the most iconic member of the Cybele pop…
Stellar angular momentum of disk galaxies at z ≈ 0.7 in the MAGIC survey. I. Impact of the environment
Ciesla, L.; Krajnović, D.; Lemaux, B. C. +6 more
Aims: At intermediate redshift, galaxy groups and clusters are thought to impact galaxy properties such as their angular momentum. We investigate whether the environment has an impact on the galaxies' stellar angular momentum and identify underlying driving physical mechanisms.
Methods: We derived robust estimates of the stellar angular …
