Investigating 2M1155-7919B: a Nearby, Young, Low-Mass Star Actively Accreting from a Nearly Edge-on, Dusty Disk
D. Annie Dickson-Vandervelde, Joel H. Kastner, Jonathan Gagné +5
We investigate the nature of an unusually faint member of the Cha Association ( pc, age Myr), the nearest region of star formation of age 8 Myr. This objec…
Convection Reconciles the Difference in Efficiencies Between Low-Mass and High-Mass Common Envelopes
E. C. Wilson, J. Nordhaus
The formation pathways for gravitational-wave merger sources are predicted to include common envelope (CE) evolution. Observations of high-mass post-common envelope binaries sugges…
Detached Shell Carbon Stars: Tracing Thermal Pulses on the Asymptotic Giant Branch
Joel H. Kastner, Emily Wilson
We consider whether the subset of carbon-rich asymptotic giant branch (AGB) stars that exhibit detached, expanding circumstellar shells may reveal the past histories of these stars…
Gaia-based Isochronal, Kinematic, and Spatial Analysis of the Cha Association
D. Annie Dickson-Vandervelde, Emily C. Wilson, Joel H. Kastner
The precise parallax, proper motion, and photometric measurements contained in Gaia Data Release 2 (DR2) offer the opportunity to re-examine the membership and ages of Nearby Young…
Successive common envelope events from multiple planets
Luke Chamandy, Eric G. Blackman, Jason Nordhaus +1
Many stars harbour multi-planet systems. As these stars expand late in their evolutions, the innermost planet may be engulfed, leading to a common envelope (CE) event. Even if this…
Convection and Spin-Up During Common Envelope Evolution: The Formation of Short-Period Double White Dwarfs
E. C. Wilson, J. Nordhaus
The formation channels and predicted populations of double-white dwarfs (DWDs) are important because a subset will evolve to be gravitational-wave sources and/or progenitors of Typ…
The Role of Convection in Determining the Ejection Efficiency of Common Envelope Interactions
E. C. Wilson, J. Nordhaus
A widely used method for parameterizing the outcomes of common envelopes (CEs) involves defining an ejection efficiency, , that represents the fraction of orb…
