Not Single After All Planetary nebulae form toward the end of the lives of sunlike stars. They appear after the star has shed its outer layers, and radiation from what is left of it ionizes the surrounding medium. Using the Very Large Telescope in Chile, Boffin et al. (p. 773) obtained spectra of the star at the center of Fleming 1, a point-symmetric planetary nebula with rotating bipolar jets. It has long been assumed that jets like these arose from an interacting binary system. Indeed, the… 

The double-degenerate, super-Chandrasekhar nucleus of the planetary nebula Henize 2-428

It is reported that Henize 2-428 has a double-degenerate core with a combined mass of ∼1.76, which is above the Chandrasekhar limit (the maximum mass of a stable white dwarf) of 1.4, which suggests that the system should merge in 700 million years, triggering a type Ia supernova event.

(Sub)stellar companions shape the winds of evolved stars

The stellar winds of 14 stars during their asymptotic giant branch (AGB) phase of stellar evolution are observed and it is inferred that the same physics shapes both AGB winds and PNe; additionally, the morphology and AGB mass-loss rate are correlated.

An outburst powered by the merging of two stars inside the envelope of a giant

We conduct three-dimensional hydrodynamical simulations of energy deposition into the envelope of a red giant star as a result of the merger of two close main sequence stars or brown dwarfs, and show

Bipolar rings from jet-inflated bubbles around evolved binary stars

We show that a fast wind that expands into a bipolar nebula composed of two opposite jet-inflated bubbles can form a pair of bipolar rings around giant stars. Our model assumes three mass loss

The planetary nebula IC 4776 and its post-common-envelope binary central star

We present a detailed analysis of IC 4776, a planetary nebula displaying a morphology believed to be typical of central star binarity. The nebula is shown to comprise a compact hourglass-shaped

The post-common-envelope binary central star of the planetary nebula ETHOS 1

We present a detailed study of the binary central star of the planetary nebula ETHOS 1 (PN G068.1+11.0). Simultaneous modelling of light and radial velocity curves reveals the binary to comprise a

Shaping planetary nebulae with jets in inclined triple stellar systems

Abstract We conduct three-dimensional hydrodynamical simulations of two opposite jets launched obliquely to the orbital plane around an asymptotic giant branch (AGB) star and within its dense wind,

The post-common-envelope, binary central star of the planetary nebula Hen 2-11

We present a detailed photometric study of the central star system of the planetary nebula Hen 2-11, selected for study because of its low-ionisation filaments and bipolar morphology – traits which

The post-common-envelope binary central star of the planetary nebula PN G283.7−05.1

We present the discovery and characterisation of the post-common-envelope central star system in the planetary nebula PN G283.7−05.1. Deep images taken as part of the POPIPlaN survey indicate that

The post-common-envelope X-ray binary nucleus of the planetary nebula NGC 2392

Abstract The Chandra X-ray Observatory has detected relatively hard X-ray emission from the central stars of several planetary nebulae (PNe). A subset has no known late-type companions, making it



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

Proof of polar ejection from the close-binary core of the planetary nebula Abell 63

We present the first detailed kinematical analysis of the planetary nebula Abell 63, which is known to contain the eclipsing close-binary nucleus UU Sge. Abell 63 provides an important test case in

ETHOS 1: a high-latitude planetary nebula with jets forged by a post-common-envelope binary central star

We report on the discovery of ETHOS 1 (PN G068.1+11.0), the first spectroscopically confirmed planetary nebula (PN) from a survey of the SuperCOSMOS Science Archive for high-latitude PNe. ETHOS 1

The Origin and Shaping of Planetary Nebulae: Putting the Binary Hypothesis to the Test

Planetary nebulae (PNs) are circumstellar gas ejected during an intense mass-losing phase in the lives of asymptotic giant branch stars. PNs have a stunning variety of shapes, most of which are not

Double Core Evolution. X. Through the Envelope Ejection Phase

The evolution of binary systems consisting of an asymptotic giant branch star of mass equal to 3 M☉ or 5 M☉ and a main-sequence star of mass equal to 0.4 M☉ or 0.6 M☉ with orbital periods ≳200 days

Morphological and kinematic signatures of a binary central star in the planetary nebula Hu 2-1

Kinematical Evidence for a Rotating, Episodic Jet in the Planetary Nebula Fleming 1

Spatially resolved, long-slit, echelle observations have been obtained in the light of the Hα and [N II] λ6548 emission lines for the symmetric strings of ionized knots emerging from the body of the

Binary planetary nebulae nuclei towards the Galactic bulge - I. Sample discovery, period distribution, and binary fraction

Binarity has been hypothesised to play an important, if not ubiquitous, role in the formation of planetary nebulae (PNe). Yet there remains a severe paucity of known binary central stars required to
