Coevolution of Dust Growth and Gravitational Instability in Massive Protostellar Disks

Massive protostellar disks are expected to sustain high accretion rates through gravitational instability, while dust growth may modify their opacity, cooling efficiency, and stability. Conversely, the time-dependent and nonaxisymmetric structures produced by...

Phakoseismology: Asteroseismology of gravitationally microlensed stars

Asteroseismology relies on disk-integrated photometry or radial velocities, in which geometric cancellation suppresses modes of high spherical degree ($l\geq4$). Observations are thus limited to deeply penetrating, low-degree modes, leaving the outer envelope...
