The NGC 346 massive star census: Nitrogen abundances for apparently single, narrow lined, hydrogen core burning B-type stars
P. L. Dufton, C. J. Evans, D. J. Lennon +1
Analyses of large spectroscopic surveys of early-type stars in the LMC have found an excess of nitrogen enriched B-type targets with a vsini<40 km/s compared with the predictions o…
TOI-503: The first known brown dwarf-Am star binary from the TESS mission
Ján Šubjak, Rishikesh Sharma, Theron W. Carmichael +76
We report the discovery of an intermediate-mass transiting brown dwarf, TOI-503b, from the TESS mission. TOI-503b is the first brown dwarf discovered by TESS and orbits a metallic-…
ALMA resolves the hourglass magnetic field in G31.41+0.31
M. T. Beltrán, M. Padovani, J. M. Girart +9
Context. Submillimeter Array (SMA) 870 micron polarization observations of the hot molecular core G31.41+0.31 revealed one of the clearest examples up to date of an hourglass-shape…
Torus model properties of an ultra-hard X-ray selected sample of Seyfert galaxies
I. García-Bernete, C. Ramos Almeida, A. Alonso-Herrero +15
We characterize for the first time the torus properties of an ultra-hard X-ray (14-195 keV) volume-limited (DL<40 Mpc) sample of 24 Seyfert (Sy) galaxies (BCS40 sample). The sample…
Spotting the differences between active and non-active twin galaxies on kpc-scales. A pilot study
I. del Moral-Castro, B. Garcia-Lorenzo, C. Ramos Almeida +6
We present a pilot study aimed to identify large-scale galaxy properties that could play a role in activating a quiescent nucleus. To do so, we compare the properties of two isolat…
