The ultimate fates of binary companions to stars (including whether the companion survives and the final orbit of the binary) are of interest in light of an increasing number of recently discovered, low-mass companions to white dwarfs (WDs). In this Letter, we study the evolution of a two-body system wherein the orbit adjusts due to structural changes in the primary, dissipation of orbital energy via tides, and mass loss during the giant phases; previous studies have not incorporated changes in…

On the role of reduced wind mass-loss rate in enabling exoplanets to shape planetary nebulae
We use the stellar evolution code MESA-binary and follow the evolution of three exoplanets and two brown dwarfs (BDs) to determine their potential role in the future evolution of their parent star on
The future influence of six exoplanets on the envelope properties of their parent stars on the giant branches
We study the evolution of six exoplanetary systems with the stellar evolutionary code mesa and conclude that they will likely spin-up the envelope of their parent stars on the red giant branch (RGB)
The grain size survival threshold in one-planet post-main-sequence exoplanetary systems
The size distribution and orbital architecture of dust, grains, boulders, asteroids, and major planets during the giant branch phases of evolution dictate the preponderance and observability of the
The post-main-sequence fate of the HR 8799 planetary system
The noteworthy four-planet HR 8799 system teeters on the brink of gravitational instability and contains an A-type host star which is characteristic of the progenitors of the majority of known white
The great escape - III. Placing post-main-sequence evolution of planetary and binary systems in a Galactic context
Our improving understanding of the life cycle of planetary systems prompts investigations of the role of the Galenvironment before, during and after asymptotic giant branch (AGB) stellar evolution.
How Jupiters Save or Destroy Inner Neptunes around Evolved Stars
In about 6 Gyr our Sun will evolve into a red giant and finally end its life as a white dwarf. This stellar metamorphosis will occur to virtually all known host stars of exoplanetary systems and is
The unstable fate of the planet orbiting the A-star in the HD 131399 triple stellar system
Validated planet candidates need not lie on long-term stable orbits, and instability triggered by post-main-sequence stellar evolution can generate architectures which transport rocky material to
A Jovian analogue orbiting a white dwarf star.
The non-detection of a main-sequence lens star in the microlensing event MOA-2010-BLG-477Lb12 using near-infrared observations from the Keck Observatory is reported, which is evidence that planets around white dwarfs can survive the giant and asymptotic giant phases of their host's evolution, and supports the prediction that more than half ofwhite dwarfs have Jovian planetary companions.
Long-term evolution of three-planet systems to the post-main sequence and beyond
We study the stability of systems of three giant planets orbiting 3-8 M☉ stars at orbital distances of >10 au as the host star ages through the main sequence (MS) and well into the white dwarf (WD)
Close-in planets are in jeopardy, as their host stars evolve off the main sequence (MS) to the subgiant and red giant phases. In this paper, we explore the influences of the stellar mass (in the


Binary Evolution Leads to Two Populations of White Dwarf Companions
Planets and other low-mass binary companions to stars face a variety of potential fates as their host stars move off the main sequence and grow to subgiants and giants. Stellar mass loss tends to
Tides and tidal engulfment in post-main-sequence binaries: period gaps for planets and brown dwarfs around white dwarfs
The presence of a close, low-mass companion is thought to play a substantial and perhaps necessary role in shaping post-Asymptotic Giant Branch and Planetary Nebula outows. During post-main-sequence
The great escape – II. Exoplanet ejection from dying multiple-star systems
Extrasolar planets and belts of debris orbiting post-main-sequence single stars may become unbound as the evolving star loses mass. In multiple-star systems, the presence or co-evolution of the
An AMR Study of the Common-envelope Phase of Binary Evolution
The hydrodynamic evolution of the common-envelope (CE) phase of a low-mass binary composed of a 1.05 M☉ red giant and a 0.6 M☉ companion has been followed for five orbits of the system using a
Shrinking binary and planetary orbits by Kozai cycles with tidal friction
At least two arguments suggest that the orbits of a large fraction of binary stars and extrasolar planets shrank by 1-2 orders of magnitude after formation: (1) the physical radius of a star shrinks
The initial–final mass relationship of white dwarfs revisited: effect on the luminosity function and mass distribution
The initial-final mass relationship connects the mass of a white dwarf with the mass of its progenitor in the main-sequence. Although this function is of fundamental importance to several fields in
Formation of high-field magnetic white dwarfs from common envelopes
It is shown that disk-generated fields are sufficiently strong to explain the observed range of magnetic field strengths for isolated, high-field magnetic white dwarfs and a higher-mass binary analogue may also contribute to the origin of magnetar fields.
Low-Mass Binary Induced Outflows from Asymptotic Giant Branch Stars
A significant fraction of planetary nebulae (PNe) and protoplanetary nebulae (PPNe) exhibit aspherical, axisymmetric structures, many of which are highly collimated. The origin of these structures is
Infrared studies have revealed debris likely related to planet formation in orbit around ∼30% of youthful, intermediate mass, main-sequence stars. We present evidence, based on atmospheric pollution
Survival of a brown dwarf after engulfment by a red giant star
The discovery of a brown dwarf in a short period orbit around a white dwarf is reported and the properties of both stars can be directly observed and show that the brown dwarf was engulfed by a red giant but that this had little effect on it.
