Photoevaporation from Inner Protoplanetary Disks Confronted with Observations
Yiren Lin, Lile Wang, Min Fang +2
The decades-long explorations on the dispersal of protoplanetary disks involve many debates about photoevaporation versus magnetized wind launching mechanisms. This letter argues t…
Observation of nonaxisymmetric standard magnetorotational instability induced by a free-shear layer
Yin Wang, Fatima Ebrahimi, Hongke Lu +3
The standard magnetorotational instability (SMRI) is widely believed to be responsible for the observed accretion rates in astronomical disks. It is a linear instability triggered…
Surprising Spin-orbit Resonances of Rocky Planets
Henry Yuan, Yubo Su, Jeremy Goodman
Recent works suggest that, in multiplanetary systems, a close-in exoplanet can sometimes avoid becoming tidally locked to its host star if it is captured into a secular spin-orbit…
Non-ideal Magnetohydrodynamic Instabilities in Protoplanetary Disks: Vertical Modes and Reflection Asymmetry
Lile Wang, Sheng Xu, Zhenyu Wang +2
Magnetized disk winds and wind-driven accretion are an essential and intensively studied dispersion mechanism of protoplanetary disks. However, the stability of these mechanisms ha…
