Detailed Description

Author: Bogdan Marinov, Georg Zotti (orbit computation enhancements, tails)

Some of the code in this class is re-used from the parent Planet class.

Member Function Documentation

◆ getInfoMap()

QVariantMap Comet::getInfoMap ( const StelCore * core ) const

overridevirtual

In addition to Planet::getInfoMap(), Comets provides estimates for.

tail-length-km
coma-diameter-km using the formula from Guide found by the GSoC2012 initiative at http://www.projectpluto.com/update7b.htm#comet_tail_formula

Reimplemented from StelObject.

◆ getVMagnitude() [1/2]

float Comet::getVMagnitude ( const StelCore * core ) const

overridevirtual

Override for comets.

When observer is on an "Observer" planet, the magnitude reported is heliocentric (seen from the Sun). This allows observing comets belt from far away while still seeing the tail.

Reimplemented from StelObject.

◆ getVMagnitude() [2/2]

float Comet::getVMagnitude	(	const StelCore *	core,
		const double	eclipseFactor
	)		const

overridevirtual

Override with additional.

Parameters

eclipseFactor. The factor is ignored.

Reimplemented from Planet.

◆ renderDiscoveryDesignationHtml()

static QString Comet::renderDiscoveryDesignationHtml ( const QString & plainText )

static

renders the subscript in a comet discovery designation with HTML.

This subscript only ever appears in the super rare case when a comet is first labeled as asteroid.

◆ setAbsoluteMagnitudeAndSlope()

void Comet::setAbsoluteMagnitudeAndSlope	(	const float	magnitude,
		const float	slope
	)

sets absolute magnitude and slope parameter.

These are the parameters in the IAU's two-parameter magnitude system for comets. They are used to calculate the apparent magnitude at different distances from the Sun. They are not used in the same way as the same parameters in MinorPlanet.

◆ setDiscoveryData()

void Comet::setDiscoveryData	(	const QString &	date,
		const QString &	name
	)

inline

set the discovery circumstances of comet

Parameters

date	of discovery
name	of discoverer

◆ translateName()

void Comet::translateName ( const StelTranslator & trans )

overridevirtual

sets the nameI18 property with the appropriate translation.

Function overridden to handle the problem with name conflicts.

Reimplemented from Planet.
