Tidal Truncation of Inclined Circumstellar and Circumbinary Discs in Young Stellar Binaries
read the original abstract
Recent observations have shown that circumstellar and circumbinary discs in young stellar binaries are often misaligned with respect to the binary orbital plane. We analyze the tidal truncation of such misaligned discs due to torques applied to the disc at the Lindblad resonances from the tidal forcings of the binary. We consider eccentric binaries with arbitrary binary-disc inclination angles. We determine the dependence of the tidal forcing strengths on the binary parameters and show that they are complicated non-monotonic functions of eccentricity and inclination. We adopt a truncation criterion determined by the balance between resonant torque and viscous torque, and use it to calculate the outer radii of circumstellar discs and the inner radii of circumbinary discs. Misaligned circumstellar discs have systematically larger outer radii than aligned discs, and are likely to fill their Roche lobes if inclined by more than $45^\circ - 90^\circ$, depending on the binary mass ratio and disc viscosity parameter. Misaligned circumbinary discs generally have smaller inner radii than aligned discs, but the details depend sensitively on the binary and disc parameters.

Sub-Snowline Formation of Gas-Giant Planets in Binary Systems
Gas giants form sub-snowline in binaries via dust traps at the tidal truncation radius, with observed planet semi-major axes following a_planet = 0.569 r_t (R²=0.94).

On the origin of anomalous dissipation in simulations of tidal disruption events
Anomalous pre-intersection dissipation in TDE simulations is numerical in origin, arising from pericenter kinematics combined with algorithm sensitivities to converging versus diverging flows.

Exploring the radial velocity variations of RY Lup with VLT/ESPRESSO: Binary versus spot hypotheses
RY Lup's 3.75-day RV and LSD variations are compatible with a ~0.04 au binary (q~0.6, e~0.23, i~13°) or with multi-spot activity, but both interpretations have serious physical tensions.

Dust Growth in Binary Systems: Inhibition of dust settling and growth in circumbinary discs
Dust grains in circumbinary discs end up five times smaller than in single-star discs, and the conditions for streaming-instability clumping are not met, arguing against in-situ planet formation there.

Insights from Analytical Theory of Eccentric Circumbinary Disks II. Forced Modes and Resonance for Precessing Binaries
Semi-analytical theory derives radial scalings for forced disk eccentricity (E ~ r^{-1} or r^{-2}) and resonance criteria for precessing binaries, plus a conjecture that cavity size tunes the ground eccentric mode to ...
