Constraining Tidal Migration with the Hot Jupiter Population

Linhao Ma, Yubo Su, Samuel W. Yee +3

Hot Jupiters with orbital periods shorter than a few days have probably been affected by tidal orbital migration. We develop an analytical framework for constraining tidal migratio…

A Diverse Distribution of Black Hole Spins from Stable Mass Transfer

Linhao Ma, Jakub Klencki, Eliot Quataert +1

Gravitational wave observations have found over 300 merging binary black holes, yet their origins remain uncertain. Recent work showed that many may come from isolated stellar bina…

Tidal Spin-up of Subdwarf B Stars

Linhao Ma, Jim Fuller

Hot subdwarf B (sdB) stars are stripped helium-burning stars that are often found in close binaries, where they experience strong tidal interactions. The dissipation of tidally exc…

Variability of Blue Supergiants in the LMC with TESS

Linhao Ma, Cole Johnston, Earl P. Bellinger +1

The blue supergiant (BSG) problem, namely, the overabundance of BSGs inconsistent with classical stellar evolution theory, remains an open question in stellar astrophysics. Several…

Tidal Spin-up of Black Hole Progenitor Stars

Linhao Ma, Jim Fuller

Gravitational wave observations indicate the existence of merging black holes (BHs) with high spin (), whose formation pathways are still an open question. A possible…

A New Discrete Dynamical Friction Estimator Based on -body Simulations

Linhao Ma, Philip F. Hopkins, Luke Zoltan Kelley +1

A longstanding problem in galactic simulations is to resolve the dynamical friction (DF) force acting on massive black hole particles when their masses are comparable to or less th…

Orbital Decay of Short-Period Exoplanets via Tidal Resonance Locking

Linhao Ma, Jim Fuller

A large fraction of known exoplanets have short orbital periods where tidal excitation of gravity waves within the host star causes the planets' orbits to decay. We study the effec…

Seeds Don't Sink: Even Massive Black Hole "Seeds" Cannot Migrate to Galaxy Centers Efficiently

Linhao Ma, Philip F. Hopkins, Xiangcheng Ma +3

Possible formation scenarios of supermassive black holes in the early universe include rapid growth from less massive seed black holes (BHs) via super-Eddington accretion or runawa…

Most Black Holes are Born Very Slowly Rotating

Jim Fuller, Linhao Ma

The age of gravitational wave (GW) astronomy has begun, and black hole (BH) mergers detected by LIGO are providing novel constraints on massive star evolution. A major uncertainty…

Angular momentum transport in massive stars and natal neutron star rotation rates

Linhao Ma, Jim Fuller

The internal rotational dynamics of massive stars are poorly understood. If angular momentum (AM) transport between the core and the envelope is inefficient, the large core AM upon…
