Zeta Ophiuchi: Embracing a Rejected Star | NASA Chandra
Zeta Ophiuchi is a star with a complicated past, having likely been ejected from its birthplace by a powerful stellar explosion. A new look by NASA's Chandra X-ray Observatory helps tell more of the story of this runaway star.
Located about 440 light-years from Earth, Zeta Ophiuchi is a hot star that is 20 times more massive than the Sun. Previous observations have provided evidence that Zeta Ophiuchi was once in close orbit with another star, before being ejected when this companion was destroyed in a supernova explosion. Infrared data from NASA's Spitzer Space Telescope reveal a spectacular shock wave that was formed by matter blowing away from the star's surface and slamming into gas in its path. Data from Chandra show a bubble of X-ray emission located around the star, produced by gas that has been heated by the shock wave to tens of millions of degrees.
Outlined in a recent paper, researchers have constructed the first detailed computer models of the shock wave. They have begun testing whether the models can explain the data obtained at different wavelengths, including X-ray, optical, infrared and radio observations. All three of the different computer models predict fainter X-ray emission than observed. The bubble of X-ray emission is brightest near the star, whereas two of the three computer models predict the X-ray emission should be brighter near the shock wave.
In the future researchers plan to test more complicated models with additional physics — including the effects of turbulence, and particle acceleration — to see whether the agreement with X-ray data will improve.

Zeta Ophiuchi: Embracing a Rejected Star | NASA Chandra
Summary: Zeta Ophiuchi is a single star that likely once had a companion that exploded as a supernova. The explosion sent Zeta Ophiuchi, seen in Spitzer (green and red) and Chandra data (blue), hurtling through space. X-rays from Chandra come from gas that has been heated to millions of degrees by the supernova. Researchers are working to match computational models of this object to explain data obtained at different wavelengths.

Located about 440 light-years from Earth, Zeta Ophiuchi is a hot star that is 20 times more massive than the Sun. Previous observations have provided evidence that Zeta Ophiuchi was once in close orbit with another star, before being ejected at about 100,000 miles per hour when this companion was destroyed in a supernova explosion over a million years ago.
Previously released infrared data from NASA's now-retired Spitzer Space Telescope, seen in this new composite image, reveals a spectacular shock wave (red and green) that was formed by matter blowing away from the star's surface and slamming into gas in its path. Data from Chandra shows a bubble of X-ray emission (blue) located around the star, produced by gas that has been heated by the effects of the shock wave to tens of millions of degrees.
A team of astronomers led by Samuel Green from the Dublin Institute for Advanced Studies in Ireland has constructed the first detailed computer models of the shock wave. They have begun testing whether the models can explain the data obtained at different wavelengths, including X-ray, optical, infrared and radio observations. All three of the different computer models predict fainter X-ray emission than observed. The bubble of X-ray emission is brightest near the star, whereas two of the three computer models predict the X-ray emission should be brighter near the shock wave.
In the future these researchers plan to test more complicated models with additional physics— including the effects of turbulence, and particle acceleration—to see whether the agreement with X-ray data will improve.
A paper describing these results has been accepted in the journal Astronomy and Astrophysics and a preprint is available here. The Chandra data used here was originally analyzed by Jesús Toala from the Institute of Astrophysics of Andalucia in Spain, who also wrote the proposal that led to the observations.

The Cat's Eye Nebula: Multiwavelength Data Sonification | NASA Chandra
Data sonification translates information collected by various NASA missions—such as the Chandra X-ray Observatory, Hubble Space Telescope, and Spitzer Space Telescope—into sounds.
When a star like the Sun begins to run out of helium to burn, it will blow off huge clouds of gas and dust. These outbursts can form spectacular structures such as the one seen in the Cat's Eye nebula. This image of the Cat's Eye contains both X-rays from Chandra around the center and visible light data from the Hubble Space Telescope, which show the series of bubbles expelled by the star over time. To listen to these data, there is a radar-like scan that moves clockwise emanating from the center point to produce pitch. Light that is further from the center is heard as higher pitches while brighter light is louder. The X-rays are represented by a harsher sound, while the visible light data sound smoother. The circular rings create a constant hum, interrupted by a few sounds from spokes in the data. The rising and falling pitches that can be heard are due to the radar scan passing across the shells and jets in the nebula.

The Cat's Eye Nebula | NASA's Chandra X-ray Observatory
This composite of data from NASA's Chandra X-ray Observatory and Hubble Space Telescope is a new look for NGC 6543, better known as the Cat's Eye nebula. This famous object is a so-called planetary nebula that represents a phase of stellar evolution that the Sun should experience several billion years from now. When a star like the Sun begins to run out of fuel, it becomes what is known as a red giant. In this phase, a star sheds some of its outer layers, eventually leaving behind a hot core that collapses to form a dense white dwarf star. A fast wind emanating from the hot core rams into the ejected atmosphere, pushes it outward, and creates the graceful filamentary structures seen with optical telescopes.
Chandra's X-ray data (colored in blue) of NGC 6543 shows that its central star is surrounded by a cloud of multi-million-degree gas. By comparing where the X-rays lie in relation to the structures seen in optical light by Hubble (red and purple), astronomers were able to deduce that the chemical abundances in the region of hot gas were like those in the wind from the central star and different from the outer cooler material. In the case of the Cat's Eye, material shed by the star is flying away at a speed of about 4 million miles per hour. The star itself is expected to collapse to become a white dwarf star in a few million years.

Zoom into The Cat's Eye Nebula | Hubble
The Cat's Eye Nebula (also known as NGC 6543 and Caldwell 6) is a planetary nebula in the northern constellation of Draco, discovered by William Herschel on February 15, 1786. It was the first planetary nebula whose spectrum was investigated by the English amateur astronomer William Huggins, demonstrating that planetary nebulae were gaseous and not stellar in nature. Structurally, the Hubble Space Telescope has revealed knots, jets, bubbles and complex arcs, being illuminated by the central hot planetary nebula nucleus (PNN). It is a well-studied object that has been observed from radio to X-ray wavelengths.

The Cat's Eye Nebula | Hubble
A dying star has created a fantasy-like sculpture of gas and dust. In this detailed view from the NASA/European Space Agency Hubble Space Telescope, the so-called Cat's Eye Nebula, looks like the penetrating eye of the disembodied sorcerer Sauron from the film adaptation of "Lord of the Rings."
The nebula, formally catalogued NGC 6543, is every bit as inscrutable as the J.R.R. Tolkien phantom character. Although the Cat's Eye Nebula was among the first planetary nebula ever to be discovered, it is one of the most complex planetary nebulae ever seen in space. A planetary nebula forms when Sun-like stars gently eject their outer gaseous layers to form bright nebulae with amazing twisted shapes.
