Spiral Structure Properties, Dynamics, and Evolution in MW-mass Galaxy Simulations
J. R. Quinn, S. R. Loebman, K. J. Daniel +8
The structure of spiral galaxies is essential to understanding the dynamics and evolution of disk galaxies; however, the precise nature of spiral arms remains uncertain. Two challe…
The Galactic Bulge exploration V.: The secular spherical and X-shaped Milky Way bulge
Z. Prudil, V. P. Debattista, L. Beraldo e Silva +9
In this work, we derive systemic velocities and subsequently orbits for 8456 RR~Lyrae stars. We identify interlopers from other Milky Way (MW) structures, which amount to 22 percen…
Shaping Galactic Habitability: the impact of stellar migration and gas giants
E. Spitoni, M. Palla, L. Magrini +9
In exoplanet research, the focus is increasingly on identifying Earth analogs, planets similar in density and habitability potential. As the number of rocky exoplanets grows, paral…
The Galactic Bulge exploration IV.: RR~Lyrae stars as traces of the Galactic bar -- 3D and 5D analysis, extinction variation
Z. Prudil, A. Kunder, L. Beraldo e Silva +10
We created new reddening maps and derived new extinction laws from visual to near-infrared passbands using improved RR~Lyrae period-absolute magnitude-metallicity relations, thus e…
Characterisation of high velocity stars in the S-PLUS internal fourth data release
F. Quispe-Huaynasi, F. Roig, V. M. Placco +7
In general, the atypical high velocity of some stars in the Galaxy can only be explained by invoking acceleration mechanisms related to extreme astrophysical events in the Milky Wa…
