TL;DR: It is demonstrated that the BMFS achieves enhanced ES for all PV serotypes in an endemic country and more frequent PV detection in BMFS compared to two-phase samples is likely due to the greater effective volume assayed.
Journal ArticleDOI
Textures and isotopic compositions of carbonaceous materials in A and B-type Stardust tracks: Track 130 (Bidi), track 141 (Coki) and track 80 (Tule)
TL;DR: In this article, the authors analyzed carbonaceous materials in the two main morphological types of Stardust tracks (A, and B) and found carbon associated with 16 of them, covering most of the range of morphologies observed in primitive meteorites and interplanetary dust particles.
High Precision Oxygen Three Isotope Analysis of Wild-2 Particles and Anhydrous Chondritic Interplanetary Dust Particles
Daisuke Nakashima,Takayuki Ushikubo,Michael E. Zolensky,M. K. Weisberg,David J. Joswiak,Donald E. Brownlee,Graciela Matrajt,Noriko T. Kita +7 more
TL;DR: In this paper, the authors reported new results of high precision oxygen isotope analyses of Wild-2 particles and anhydrous chondritic IDPs, and discuss the relationship between the cometary dust and carbonaceous chondrite chondrules.
