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, ... -
Effects of 7 MeV proton irradiation on microstructural, morphological, optical, and electrical properties of fluorine-doped tin oxide thin films
Oryema, Bosco; Jurua, Edward; Madiba, Itani G.; Ahmad, Ishaq; Aisida, Samson O.; Ezema, Fabian I.; Maaza, Malik (Elsevier, 2021-12-18) -
Effects of low-dose γ-irradiation on the structural, morphological, and optical properties of fluorine-doped tin oxide thin films
Oryema, Bosco; Jurua, Edward; Madiba, Itani G.; Nkosi, Mlungisi; Sackey, Juliet; Maaza, Malik (Radiation Physics and Chemistry, 2020-07-1)This paper presents the effects of low-dose γ-irradiation on the structural, morphological, and optical properties of Fluorine-doped tin oxide (FTO) thin films for application as a passive thermal control coating in future ... -
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 ... -
Planetary core formation via multispecies pebble accretion
Andama, Geoffrey; Ndugu, Nelson; Anguma, Simon Katrini; Jurua, Edward (Oxford University Press, 2021-12-02)In the general classical picture of pebble-based core growth, planetary cores grow by accretion of single pebble species. The growing planet may reach the so-called pebble isolation mass, at which it induces a pressure ... -
The role of density perturbation on planet formation by pebble accretion
Andama, G.; Ndugu, Nelson; Anguma, Simon Katrini; Jurua, Edward (arXiv preprint, 2022-01-28)Protoplanetary discs exhibit a diversity of gaps and rings of dust material, believed to be a manifestation of pressure maxima commonly associated with an ongoing planet formation and several other physical processes. ... -
The Status of space science and astrophysics education in Uganda
Jurua, Edward (2023-09-29)The presentation reports on human resource development space science, and astrophysics in Uganda -
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 ...
