Very massive stars : mass determination and fate / Norhasliza binti Yusof by Yusof, Norhasliza

“…In this thesis, we shall describe the dependence of VMS evolution on metallicity and present stellar evolution models at various metallicities, including the e�ects of mass loss and rotation. …”

Atomic-scale Element and Isotopic Investigation of 25 Mg-rich Stardust from an H-burning Supernova by Nevill, Neville D., Bland, Phil, Saxey, David, Rickard, William, Guagliardo, P., Timms, Nick, Forman, Lucy, Daly, Luke, Reddy, Steven

“…Presolar grains within primitive astromaterials retain records of processes and environmental changes throughout stellar evolution. However, accessing these records has proved challenging due to the average grain size (∼150 nm) of presolar silicates, their sensitivity to extraction agents, and instrumental restrictions, limiting the range of isotopic and chemical signatures which can be studied per grain volume. …”

Reliability of the double-folding potential for fusion cross sections of light systems by Abdul Aziz, Azni, Yusof, Norhasliza, Firihu, Muhammad Zamrun, Abu Kassim, Hasan

“…In the important range of temperatures in stellar evolution, the DFC potential reproduces very satisfactory fitting to the experimental cross section and the S-factor data and gives a consistent prediction of astrophysical reaction rates. …”

SCORPIO: A deep survey of radio emission from the stellar life-cycle by Umana, G., Trigilio, C., Franzen, Thomas, Norris, R., Leto, P., Ingallinera, A., Buemi, C., Agliozzo, C., Cavallaro, F., Cerrigone, L.

“…Radio emission has been detected in a broad variety of stellar objects from all stages of stellar evolution. However, most of our knowledge originates from targeted observations of small samples, which are strongly biased to sources which are peculiar at other wavelengths. …”

Electron-positron pair-production and neutrino energy-loss from the instability regions of very massive stars / Lurwan Garba Gaya by Lurwan , Garba Gaya

“…In spite of tremendous developments recorded in recent times, state-of-the-art stellar evolution models would provide many information about instability of very-massive stars arising from eminent production of electron-positron pairs. …”

Host Galaxy Properties and Offset Distributions of Fast Radio Bursts: Implications for Their Progenitors by Heintz, K.E., Prochaska, J.X., Simha, S., Platts, E., Fong, W.F., Tejos, N., Ryder, S.D., Aggerwal, K., Bhandari, S., Day, C.K., Deller, A.T., Kilpatrick, C.D., Law, C.J., Macquart, Jean-Pierre, Mannings, A., Marnoch, L.J., Sadler, E.M., Shannon, Ryan

Dust in galaxies throughout cosmic time by Rowlands, Kate

“…However, around half of all energy ever emitted from galaxies has been absorbed and reprocessed by dust, which is an end-product of stellar evolution. In order to obtain a more complete understanding of galaxy evolution, sensitive observations in the far-infrared and submillimetre are required where the dust emission peaks. …”

The characteristics of be star in delta scorpii system / Nazhatulshima Ahmad by Nazhatulshima, Ahmad

“…Our evolutionary model generated using EV stellar evolution code showed that the star is rotating at ~0.5 of critical velocity, cr, lower than the rotation which was suggested for the Be phenomenon to happen i.e 0.7cr. …”
