Dust ion acoustic double layers in a 4-component dusty plasma
Habumugisha, Isaac; Anguma, Simon Katrini; Jurua, Edward; Nazziwa, L. (Springer, 2018-02-22)In this paper, we study the Dust ion acoustic (DIA) solitons in an unmagnetised dusty plasma comprising of cold dust particles, electrons that follow Cairns distribution, warm inertial ions, and ion-beams of equal mass, ... -
New red giant star in the Kepler open cluster NGC 6819
Komucyeya, Esther; Abedigambab, O.P.; Jurua, Edward; Anguma, Simon Katrini (Elsevier, 2018)A recent study indicated that 39 red giant stars showing solar-like oscillations were discovered in the field of Kepleropen cluster NGC 6819. The study was based on photometric distance estimates of 27 stars out of the 39. ... -
Non-Linear Ion-Acoustic Solitary Waves in Electron-Positron-Ion Plasma with Non-Thermal Electrons.
Anguma, Simon Katrini; Habumugisha, Isaac; Nazziwa, L.; Jurua, Edward; Noreen, N. (Scientific Research Publishing, 2017-05-26)Ion-acoustic solitary (IAS) waves in electron-positron-ion (e-p-i) plasma have been of interest to many researchers probably due to their relevance in understanding the Universe. However, the study of non-linear ion-acoustic ... -
On the structure of quasi-Keplerian accretion discs surrounding millisecond X-ray pulsars
Habumugisha, Isaac; Tessema, Solomon B.; Jurua, Edward; Anguma, Simon Katrini (Springer, 2020-10-12)In this study, we investigated the time-independent dynamics (disc structure, forces and torques) of a quasi-Keplerian disc around a millisecond pulsar (MSP) with an internal dynamo. We considered the disc around a MSP to ... -
Onset of linear instability in a complex plasma with cairns distributed electrons
Habumugisha, Isaac; Anguma, Simon Katrini; Jurua, Edward; Noreen, N. (Scientific Research Publishing, 2016-03-07)A rigorous theoretical investigation of linear dust ion acoustic (DIA) solitary waves in an unmagnetized complex plasma consisting of ion and ion beam fluids, nonthermal electrons that are Cairns distributed and immobile ... -
Spatio-Temporal Variation in the Concentration of Inhalable Particulate Matter (PM10) in Uganda.
Onyango, Silver; Parks, Beth; Anguma, Simon Katrini; Meng, Qingyu (MDPI AG, 2019-05-17)Long-term particulate matter (PM10) measurements were conducted during the period January 2016 to September 2017 at three sites in Uganda (Mbarara, Kyebando, and Rubindi) representing a wide range of urbanization. Spatial, ... -
The structure of a Quasi-Keplerian accretion disk around magnetized stars
Habumugisha, Isaac; Jurua, Edward; Tessema, Solomon B; Anguma, Simon Katrini (The American Astronomical Society, 2018-06-04)In this paper, we present the complete structure of a quasi-Keplerian thin accretion disk with an internal dynamo around a magnetized neutron star. We assume a full quasi-Keplerian disk with the azimuthal velocity deviating ... -
Validation of the atmospheric boundary layer height estimated from the MODIS atmospheric profile data at an equatorial site
Onyango, Silver; Anguma, Simon Katrini; Andima, Geodfrey; Parks, Beth (MDPI, 2020-08-26)The atmospheric boundary layer height is important for constraining air pollution and meteorological models. This study attempted to validate the MODIS-estimated atmospheric boundary layer height (ABLH), and variation in ...
