NGC 6302 (also called the Bug Nebula, Butterfly Nebula, or Caldwell 69) is abipolarplanetary nebulain the constellationScorpius. The structure in the nebula is among the

most complex ever observed in planetary nebulae. The spectrum of NGC 6302 shows

that its central star is one of the hottest stars in the galaxy, with a surface temperature in

excess of 200,000 K, implying that the star from which it formed must have been very

large (cf.PG 1159 star).

The central star, awhite dwarf, was only recently discovered (Szyszka et al. 2009),

using the upgradedWide Field Camera 3on board theHubble Space Telescope. Thestar has a current mass of around 0.64 solar masses. It is surrounded by a particularly

dense equatorial disc composed of gas and dust. This dense disc is postulated to have

caused the star's outflows to form a bipolar structure (Gurzadyan 1997) similar to an

hour-glass. This bipolar structure shows many interesting features seen in planetary

nebulae such as ionization walls, knots and sharp edges to the lobes.

Observation history

As it is included in theNew General Catalogue, this object has been known since at

least 1888.[8]

The earliest known study of NGC 6302 is byEdward Emerson Barnard,

who drew and described it in 1907 (Meaburn et al. 2005).

Since then it has been the focus of many works and displays many interesting

characteristics worthy of study. Interest in recent years has shifted from discussions

over the excitation method in the nebula (shock-excitation or photo-ionisation) to the

properties of the large dust component.

It featured in some of the first images released after the final servicing mission of the

Hubble Space Telescope in September 2009.[9]

Characteristics

NGC 6302 has a complex morphology, which may be approximated as bipolar with two

primary lobes, though there is evidence for a second pair of lobes that may have

belonged to a previous phase of mass loss. A dark lane runs through the waist of the

nebula obscuring the central star at all wavelengths (Matsuura et al. 2005). Observations

of NGC 6302 suggest that there may be an orthogonal skirt (orchakram) similar to that

found inMenzel 3(Meaburn et al. 2005). The nebula is orientated at an angle of 12.8

against the plane of the sky.

This planetary nebula contains a prominent northwest lobe which extends up to 3.0

away from the central star and is estimated to have formed from an eruptive event

around 1,900 years ago. It has a circular part whose walls precisely follow a Hubble-

type outflow (where outflow speed is proportional to distance from the central source).

At an angular distance of 1.71 from the central star, the flow velocity of this lobe is

measured to be 263 km/s. At the extreme periphery of the lobe, the outward velocity

exceeds 600 km/s. The western edge of the lobe displays characteristics suggestive of a

collision with pre-existing globules of gas which modified the outflow in that region

(Meaburn et al. 2005).

Central star

The central star, among the hottest stars known, had escaped detection because of acombination of its high temperature (so that it radiates mainly in the ultraviolet), the

dusty torus (which absorbs a large fraction of the light from the central regions,

especially in the ultraviolet) and the bright background from the star. It was not seen in

the first HST images (APoD 2004). But the improved resolution and sensitivity of the

newWide Field Camera 3of theHubble Space Telescoperevealed the faint star at the

centre (Szyszka et al. 2009). A temperature of 200,000 Kelvin is indicated, and a mass

of 0.64 solar masses. The original mass of the star was much higher, but most was

ejected in the event which created the planetary nebula. The luminosity and temperature

of the star indicate it has ceased nuclear burning and is on its way to becoming awhite

dwarf, fading at a predicted rate of 1% per year.

Dust chemistry

The prominent dark lane that runs through the centre of the nebula has been shown to

have an extraordinary dust chemistry, showing evidence for multiple crystalline

silicates, crystalline water ice andquartz, with other features which have been

interpreted as the first extra-solar detection of carbonates (Kemper et al. 2002). This

detection has been disputed, due to the difficulties in forming carbonates in a non-

aqueous environment (Ferrarotti & Gail 2005). The dispute remains unresolved.

One of the most interesting characteristics of the dust detected in NGC 6302 is the

existence of both oxygen-rich material (i.e. silicates) and carbon-rich material (i.e. poly-

aromatic-hydrocarbons or PAHs) (Kemper et al. 2002). Stars are usually either O-rich

or C-rich, the change from the former to the latter occurring late in the evolution of the

star due to nuclear and chemical changes in the star's atmosphere. NGC 6302 belongs to

a group of objects where hydrocarbon molecules formed in an oxygen-rich environment

(Matsuura et al. 2005).
