The TESS-SPOC FFI target sample explored with Gaia
Bayliss, Daniel; Armstrong, David J.; Rodel, Toby +2 more
The Transiting Exoplanet Survey Satellite (TESS) mission has provided the community with high-precision times-series photometry for ~2.8 million stars across the entire sky via the full frame image (FFI) light curves produced by the TESS Science Processing Operations Center (SPOC). This set of light curves is an extremely valuable resource for the…
X-raying the ζ Tau binary system
Smith, Myron A.; Nazé, Yaël; Rauw, Gregor +2 more
Context. The Be star ζ Tau was recently reported to be a γ Cas analog; that is, it displays an atypical (bright and hard) X-ray emission. The origin of these X-rays remains debated.
Aims: The first X-ray observations indicated a very large absorption of the hot plasma component (NH ~ 1023 cm−2). This is most p…
The enigmatic multiple star VV Ori
Blackford, Mark G.; Southworth, John; Budding, Edwin +6 more
New photometry, including TESS data, have been combined with recent spectroscopic observations of the Orion Ib pulsating triple-star system VV Ori. This yields a revised set of absolute parameters with increased precision. Two different programmes were utilized for the light-curve analysis, with results in predictably close agreement. The agreemen…
Influence of the Jovian Current Sheet Models on the Mapping of the UV Auroral Footprints of Io, Europa, and Ganymede
André, N.; Hue, V.; Rabia, J. +4 more
The in situ characterization of moon-magnetosphere interactions at Jupiter and the mapping of moon auroral footpaths require accurate global models of the magnetospheric magnetic field. In this study, we compare the ability of two widely-used current sheet models, Khurana-2005 (KK2005) and Connerney-2020 (CON2020) combined with the most recent int…
Euclid: High-precision imaging astrometry and photometry from Early Release Observations: I. Internal kinematics of NGC6397 by combining Euclid and Gaia data
Altieri, B.; Cimatti, A.; Baccigalupi, C. +175 more
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 deg2. This exquisite image quality has the potential to produce high-precision astrometry for point sources once the undersampling of Euclid's cameras is taken into account …
The GAPS programme at TNG. LVII. TOI-5076b: A warm sub-Neptune planet orbiting a thin-to-thick-disk transition star in a wide binary system
Scandariato, G.; Pagano, I.; Winn, J. N. +36 more
Aims: We report the confirmation of a new transiting exoplanet orbiting the star TOI-5076.
Methods: We present our vetting procedure and follow-up observations which led to the confirmation of the exoplanet TOI-5076b. In particular, we employed high-precision TESS photometry, high-angular-resolution imaging from several telescopes, and h…
Gaia23bab: A New EXor
Ábrahám, P.; Nagy, Z.; Schisano, E. +11 more
On 2023 March 6, the Gaia telescope alerted a 2 mag burst from Gaia23bab, a young stellar object in the Galactic plane. We observed Gaia23bab with the Large Binocular Telescope obtaining optical and near-infrared spectra close in time to the peak of the burst, and collected all public multiband photometry to reconstruct the historical light curve.…
Herschel Gould Belt Survey in Taurus - II. A census of dense cores and filaments in the TMC1 region
Arzoumanian, D.; Könyves, V.; Palmeirim, P. +12 more
We present a catalogue of dense cores and filaments in a $3.8^\circ \times 2.4^\circ$ field around the TMC1 region of the Taurus molecular cloud. The catalogue was created using photometric data from the Herschel SPIRE and PACS instruments in the 70, 160, 250, 350, and 500 µm continuum bands. Extended structure in the region was reconstructe…
Internal 1000 au Scale Structures of the R CrA Cluster-forming Cloud. I. Filamentary Structures
Inoue, Tsuyoshi; Shoshi, Ayumu; Harada, Naoto +17 more
We report Atacama Large Millimeter/submillimeter Array/Atacama Compact Array observations of a high-density region of the Corona Australis cloud forming a young star cluster, and the results of resolving internal structures. In addition to embedded Class 0/I protostars in the continuum, a number of complex dense filamentary structures are detected…
Gaia GraL: Gaia DR2 gravitational lens systems - VIII. A radio census of lensed systems
Djorgovski, S. G.; Mignard, François; Connor, Thomas +26 more
We present radio observations of 24 confirmed and candidate strongly lensed quasars identified by the Gaia Gravitational Lenses working group. We detect radio emission from eight systems in 5.5 and 9 GHz observations with the Australia Telescope Compact Array (ATCA), and 12 systems in 6 GHz observations with the Karl G. Jansky Very Large Array (VL…
