Euclid: The convective-transition gap of 47 Tuc
M. Libralato, M. Griggio, R. Gerasimov +140
We report the first detection of the `convective-transition gap' (also known as `M-dwarf gap') in the globular cluster 47 Tuc (NGC 104) thanks to Euclid data. This feature, linked…
Unveiling the nature of HE 0107-5240
E. Caffau, M. Steffen, P. Molaro +27
The vast majority of the most iron-poor stars in the Galaxy exhibit a strong carbon enhancement, with C/H ratios only about two orders of magnitude below solar. This unusual chemic…
Stellar-activity analysis of the nearby M dwarf GJ 526. Multi-dimensional Gaussian-process modelling of RV, FWHM and S-index
A. K. Stefanov, J. I. González Hernández, A. Suárez Mascareño +17
M dwarfs are the most abundant stars in the Galaxy, and their low masses make them natural favourites for exoplanet radial-velocity (RV) searches. Nevertheless, these stars often d…
Euclid: Quick Data Release (Q1) -- Ultracool dwarfs in the Euclid Deep Fields
A. Mohandasan, R. L. Smart, C. Reylé +180
Ultracool dwarfs (UCDs) encompass the lowest-mass stars and brown dwarfs at the substellar boundary. These intrinsically faint objects are challenging to detect, but the wide cover…
Euclid: Quick Data Release (Q1) -- A photometric search for ultracool dwarfs in the Euclid Deep Fields
M. Žerjal, C. Dominguez-Tagle, N. Vitas +178
We present a catalogue of 5306 new ultracool dwarf (UCD) candidates in the three Euclid Deep Fields in the Q1 data release. They range from late M to late T dwarfs, and include 120…
Euclid: High-precision imaging astrometry and photometry from Early Release Observations. I. Internal kinematics of NGC 6397 by combining Euclid and Gaia data
M. Libralato, L. R. Bedin, M. Griggio +175
The instruments at the focus of the Euclid space observatory offer superb, diffraction-limited imaging over an unprecedented (from space) wide field of view of 0.57 deg. This e…
The physical properties of T Pyx as measured by MUSE I. The geometrical distribution of the ejecta and the distance to the remnant
L. Izzo, L. Pasquini, E. Aydi +8
T Pyx is one of the most enigmatic recurrent novae, and it has been proposed as a potential Galactic type-Ia supernova progenitor. Using spatially-resolved data obtained with MUSE,…
Ultracool dwarfs candidates based on six years of the Dark Energy Survey data
M. dal Ponte, B. Santiago, A. Carnero Rosell +57
We present a sample of 19,583 ultracool dwarf candidates brighter than z selected from the Dark Energy Survey DR2 coadd data matched to VHS DR6, VIKING DR5 and AllWISE co…
The pristine nature of SMSS 16051443 revealed by ESPRESSO
D. S. Aguado, E. Caffau, P. Molaro +20
SMSS J160540.18144323.1 is the carbon-enhanced metal-poor (CEMP) star with the lowest iron abundance ever measured, [Fe/H]=-6.2, which was first reported with the SkyMapper tele…
Espresso observations of HE 01075240 and other CEMP-no stars with
D. Aguado, P. Molaro, E. Caffau +22
HE 01075240 is a hyper metal-poor star with . We performed high-res observations with the ESPRESSO spectrograph at the VLT to constrain the kinematical propert…
7Be detection in the 2021 outburst of RS Oph
P. Molaro, L. Izzo, P. Selvelli +7
The recurrent nova RS Oph underwent a new outburst on August 8, 2021, reaching a visible brightness of V = 4.8 mag. Observations of the 2021 outburst made with the high resolution…
Accretion and Outflows in Young Stars with CUBES
J. M. Alcalá, G. Cupani, C. J. Evans +2
The science case on studies of accretion and outflows in low-mass (1.5 ) young stellar objects (YSOs) with the new CUBES instrument is presented. We show the need for…
Detection of Be II in the Small Magellanic Cloud
Luca Izzo, Paolo Molaro, Gabriele Cescutti +8
We analyse high resolution spectra of two classical novae that exploded in the Small Magellanic Cloud. Be II resonance transitions are detected in both ASASSN-19qv and ASASSN-2…
7Be in the outburst of the ONe nova V6595 Sgr
P. Molaro, L. Izzo, V. D'Odorico +7
We report the search for 7Be isotope in the outbursts of the classical nova V6595 Sgr by means of high resolution UVES observations taken at the ESO VLT in April 2021, about two we…
Young giants of intermediate mass Evidence of rotation and mixing
Linda Lombardo, Patrick François, Piercarlo Bonifacio +7
In the search of a sample of metal-poor bright giants using Str{ö}mgren photometry, we serendipitously found a sample of 26 young (ages younger than 1 Gyr) metal-rich giants, some…
Barium lines in high-quality spectra of two metal-poor giants in the Galactic halo
G. Cescutti, C. Morossi, M. Franchini +9
Context. Theoretical results showed the possibility that neutron capture elements were produced in the early Universe by two different sources: a frequent s-process source hosted b…
Solar-Cycle Variations of South-Atlantic Anomaly Proton Intensities Measured With The PAMELA Mission
A. Bruno, M. Martucci, F. S. Cafagna +50
We present a study of the solar-cycle variations of >80 MeV proton flux intensities in the lower edge of the inner radiation belt, based on the measurements of the Payload for Anti…
On the mass and metallicity distribution of parent AGB stars of presolar SiC
Sergio Cristallo, Ambra Nanni, Gabriele Cescutti +5
The vast majority (>=90%) of presolar SiC grains identified in primitive meteorites are relics of ancient asymptotic giant branch (AGB) stars, whose ejecta were incorporated into t…
The solar gravitational redshift from HARPS-LFC Moon spectra. A test of the General Theory of Relativity
J. I. González Hernández, R. Rebolo, L. Pasquini +15
The General Theory of Relativity predicts the redshift of spectral lines in the solar photosphere, as a consequence of the gravitational potential of the Sun. This effect can be me…
