Context
An approximation known as the Tisserand criteria (T) is applied to cometary encounters with planets (such as Jupiter) and used to describe their orbital inter-relationship. Asteroidal-appearing bodies in elliptical orbits with Jovian Tisserand parameters Tj < 3 only began to appear in search programs in the mid-1980’s - Kridsadaporn's Jovian Tisserand parameter is Tj = 2.858. Before this, the failure to identify these objects was used as an argument against the existence of extinct cometary nuclei. Over the past two decades, an increasing number of asteroids, based upon their orbital and physical characteristics, have been suggested as extinct or dormant comets candidates. It is now considered likely that within the asteroid population there exist a significant number of dormant or extinct comets.
More recently, Kridsadaporn has received closer attention after having been included in a number of studies relating to the analysis of spectral properties of asteroids in cometary orbits (ACOs); and, collisional activation processes, and the dynamic and physical properties of ACOs. The investigation of ACOs is considered important in the understanding of formation processes of cometary dust mantles and the end states of comets, so as to determine the population of Jupiter family comets (JFCs), and, to also understand the dynamical processes involved in the transport mechanism of asteroids from typical asteroidal orbits to cometary-like ones.
In earlier studies, ACOs have sometimes been referred to as cometary asteroids or comet-asteroid transition objects.

Famous quotes containing the word context:
“The hippie is the scion of surplus value. The dropout can only claim sanctity in a society which offers something to be dropped out of—career, ambition, conspicuous consumption. The effects of hippie sanctimony can only be felt in the context of others who plunder his lifestyle for what they find good or profitable, a process known as rip-off by the hippie, who will not see how savagely he has pillaged intricate and demanding civilizations for his own parodic lifestyle.”
—Germaine Greer (b. 1939)
“Parents are led to believe that they must be consistent, that is, always respond to the same issue the same way. Consistency is good up to a point but your child also needs to understand context and subtlety . . . much of adult life is governed by context: what is appropriate in one setting is not appropriate in another; the way something is said may be more important than what is said. . . .”
—Stanley I. Greenspan (20th century)
“The hard truth is that what may be acceptable in elite culture may not be acceptable in mass culture, that tastes which pose only innocent ethical issues as the property of a minority become corrupting when they become more established. Taste is context, and the context has changed.”
—Susan Sontag (b. 1933)
