Homoclinic tangencies leading to robust heterodimensional cycles
Pablo G. Barrientos, Lorenzo J. Díaz, Sebastián A. Pérez
We consider () diffeomorphisms defined on manifolds of dimension with homoclinic tangencies associated to saddles. Under generic properties, w…
High-resolution ALMA observations of V4046Sgr: a circumbinary disc with a thin ring
Rafael Martinez-Brunner, Simon Casassus, Sebastián Pérez +8
The nearby V4046 Sgr spectroscopic binary hosts a gas-rich disc known for its wide cavity and dusty ring. We present high resolution (20 mas or 1.4 au) ALMA observations of t…
The steady-state hydrodynamics of a long-lived disc: planetary system architecture and prospects of observing a circumplanetary disc shadow in V4046Sgr
Philipp Weber, Simon Casassus, Sebastián Pérez
Recent imaging of the disc around the V4046Sgr spectroscopic binary revealed concentric regions of dust rings and gaps. The object's proximity and expected equilibrated state d…
Millimeter-sized Dust Grains Appear Surviving the Water-sublimating Temperature in the Inner 10 au of the FU Ori Disk
Hauyu Baobab Liu, An-Li Tsai, Wen Ping Chen +10
Previous observations have shown that the 10 au, 400 K hot inner disk of the archetypal accretion outburst young stellar object, FU Ori, is dominated by viscous…
