262LBNFp
'262LBNFp' is a designation within the field of astronomy, specifically related to the classification of variable stars. Here are some key points about this designation:
-
Variable Star Designation: The term "262LBNFp" refers to a type of variable star known as a Mira variable, which exhibits large amplitude pulsations over long periods. The designation is part of the GCVS (General Catalogue of Variable Stars) classification system.
-
Periodicity: Mira variables, like those with the 'LBNFp' suffix, have periods that can range from 80 to 1000 days, with 262LBNFp indicating a specific variability pattern within this range.
-
Amplitude: These stars experience significant changes in brightness, with amplitudes typically exceeding 2.5 magnitudes in the V band (visual spectrum). The 'LBNFp' classification suggests a particular pattern of brightness variation.
-
Evolutionary Stage: Mira variables are generally in the late stages of their evolution, having evolved off the main sequence and into the asymptotic giant branch (AGB) phase where they undergo pulsations due to thermal pulses.
-
Observation: Observations of 262LBNFp type stars are crucial for understanding stellar evolution, especially the processes involved in mass loss and the production of circumstellar dust. These observations are often carried out by amateur astronomers as part of variable star observing programs.
-
History: The classification system was developed by astronomers like B. V. Kukarkin, who contributed significantly to the field of variable star research in the 20th century. The specific designation '262LBNFp' would have been cataloged based on observations and analysis of light curves.
