IGR J17329-2731 [1] as described by European Space Agency astronomers is a single faint transient X-ray source (ATel #10644) observed with Swift/XRT on 16 August 2017 from 2:26 to 2:45 UTC with an effective exposure of time of 1 ks. It was detected within the positional uncertainty provided by INTEGRAL IBIS imagery. [2]
Indexing and classification methods to assist with information retrieval have a long history dating back to the earliest libraries and collections however systematic evaluation of their effectiveness began in earnest in the 1950s with the rapid expansion in research production across military, government and education and the introduction of computerised catalogues.
Iota Octantis A has a classification of K0 III, [3] which indicates that it is an evolved K-type star that exhausted hydrogen at its core and left the main sequence. It has an angular diameter of 1.07 arcseconds , [ 11 ] which yields a radius 12.43 times that of the Sun at its estimated distance. [ 7 ]
It is about 7,500 light years from Earth assuming it is a member of IC 2581, which is given a 62.9% probability. [22] Its angular diameter has been estimated at 0.954 ± 0.09 milliarcseconds , [ 23 ] which, at the estimated distance of 2009 parsecs , [ 1 ] gives it a radius 206 times the solar radius .
IGR J17091 is a stellar mass black hole with a mass between 3 and 10 M ☉. It is a binary system in which a star orbits the black hole. [4] Its small size may make it a candidate for the smallest black hole discovered. [5] However, as of 2017 its mass was described as "unknown". [6]
The Iwate Galaxy Railway Company owns a fleet of IGR 7000 series 2-car electric multiple unit (EMU) trains. The fleet consists of four 7000-0 series sets, which were originally JR East 701-1000 series sets transferred from Morioka in December 2002, and three newly built 7000-100 series sets.
