New Probability Distributions in Astrophysics: XIII. Truncation for the Benini Distribution: 《International Journal of Astronomy and Astrophysics》2024年第3期203-219,共17页Lorenzo Zaninetti; In order to introduce a right truncated version of the Benini distribution, we derive its probability density function, its distribution function, its average value, its kth moment about the origin, its median, how to...; 关键词：Stars: Normal Stars: Luminosity Function Mass Function Stars: Statistics

New Probability Distributions in Astrophysics: XII. Truncation for the Gompertz Distribution: 《International Journal of Astronomy and Astrophysics》2024年第2期101-119,共19页Lorenzo Zaninetti; Analytical functions which fit the probability distributions of stars and galaxies can provide insight into how these distributions originate. In order to introduce a truncated version of the Gompertz distribution, we...; 关键词：Stars: Normal Stars: Luminosity Function Mass Function Stars: Statistics

New Probability Distributions in Astrophysics: XI. Left Truncation for the Topp-Leone Distribution: 《International Journal of Astronomy and Astrophysics》2023年第3期154-165,共12页Lorenzo Zaninetti; The Topp-Leone (T-L) distribution has aided the modeling of scientific data in many contexts. We demonstrate how it can be adapted to model astrophysical data. We analyse the left truncated version of the T-L distribu...; 关键词：Stars: Normal Stars: Luminosity Function Mass Function Stars: Statistics

WISE Infrared Search for Young Stellar Objects Associated with Starless Cores: 《International Journal of Astronomy and Astrophysics》2023年第2期89-111,共23页Susumu Sato Yuri Iwamoto Yoichi Itoh; This study presents the results of an infrared search of young stellar objects (YSOs) associated with cores with high optical extinction and no associated infrared IRAS source. Four hundred YSO candidates were identif...; 关键词：Stars: Formation ISM: Clouds Infrared: Stars

New Probability Distributions in Astrophysics: VI. The Truncated Sujatha Distribution被引量：2: 《International Journal of Astronomy and Astrophysics》2021年第4期517-529,共13页Lorenzo Zaninetti; The truncated version of the two-parameter Sujatha distribution is analysed. In particular, its probability density function and distribution function are obtained. The results are applied to the initial mass function...; 关键词：Stars: Mass Function Galaxy Groups CLUSTERS SUPERCLUSTERS Large Scale Structure of the Universe COSMOLOGY

Optical Spectroscopic Monitoring Observations of a Young Binary Z CMa: 《International Journal of Astronomy and Astrophysics》2021年第3期406-421,共16页Hinako Akimoto Yoichi Itoh; The results of optical spectroscopic monitoring observations of a young binary system, Z CMa, are presented in this study. Z CMa consists of a Herbig Be star and an FU Orionis object, and it shows irregular light vari...; 关键词：Stars:Pre-Main Sequence Stars:Variables:T Tauri Herbig Ae/Be Techniques:Spectroscopic

New Probability Distributions in Astrophysics: V. The Truncated Weibull Distribution被引量：4: 《International Journal of Astronomy and Astrophysics》2021年第1期133-149,共17页Lorenzo Zaninetti; We demonstrate that certain astrophysical distributions can be modelled with the truncated Weibull distribution, which can lead to some insights: in particular, we report the average value, the rth moment, th...; 关键词：Stars: Normal Galaxy Groups CLUSTERS and Superclusters Large Scale Structure of the Universe COSMOLOGY
