Interacting stellar winds feeding Sgr A*: from the system of mass-losing stars to the binary IRS 16SW
Diego Calderón, Jorge Cuadra, Christopher M. P. Russell +3
The discovery of cold structures around Sgr A* has challenged our understanding of the gas dynamics and thermodynamic state of the plasma in its vicinity. This work aims to constra…
Superdiffusion at the Galactic Centre
Pau Amaro Seoane, Kostas Tzanavaris, Reinhard Genzel +14
The paper models the orbital evolution of the S‑star cluster around the Milky Way’s central black hole using a superdiffusive, fractional transport framework that accounts for long…
Stellar rotation of S301 as a macroscopic gyroscope to test general relativity
Pau Amaro Seoane, Xian Chen, Alejandro Torres-Orjuela +16
The paper studies how the rotation of the S301 star near the Galactic Center can act as a macroscopic gyroscope, using its relativistic precession to test general relativity with i…
S301 and friends: Measuring the spin of Sgr A*
T. Piran, P. Amaro-Seoane, B. Aytac +15
The discovery of S301 (GRAVITY Collaboration et al., 2026) with pericenter distance rp= 280rg and eccentricity e=0.9825, opens the prospect of measuring the spin parameter of Sgr A…
Bonnor-Ebert sphere collapse in filamentary structures
Stefan Heigl, Andreas Burkert
Star formation within filaments may arise due to the growth of cores according to linear perturbation theory. This implies a minimum core separation, as shorter modes would not be…
The formation and stability of a cold disc made out of stellar winds in the Galactic Centre
Diego Calderón, Jorge Cuadra, Christopher M. P. Russell +3
The reported discovery of a cold (~10 K) disc-like structure within 0.005 pc around the super-massive black hole at the centre of the Milky Way, Sgr A*, has challenged our unde…
