Kob Kob The kob ("Kobus kob") is an antelope found across Central Africa and parts of West Africa and East Africa. Together with the closely-related reedbucks, waterbucks, lechwe, Nile lechwe, and puku, it forms the Reduncinae tribe. Found along the northern savanna, it is often seen in Murchison Falls and Queen Elizabeth National Park, Uganda; Garamba and Virunga National Park, and the Democratic Republic of the Congo, as well as grassy floodplains of South Sudan. Kob are found in wet areas (such as floodplains), where they eat grasses. Kob are diurnal, but inactive during the heat of the day. They live
A-type main-sequence star also occasionally sees Delta Leonis (A4 V) listed as a standard. There are no published A6 V and A8 V standard stars. A-type stars are young (typically few hundred million years old) and many emit infrared (IR) radiation beyond what would be expected from the star alone. This IR excess is attributable to dust emission from a debris disk where planets form. Surveys indicate massive planets commonly form around A-type stars although these planets are difficult to detect using the Doppler spectroscopy method. This is because A-type stars typically rotate very quickly, which makes it difficult to measure the small
