Spinone Italiano conducted a breed health survey which found the average life expectancy of Italian Spinone to be 8.7 years. The breed is believed to have been developed in the Piedmont region of Italy. As the Spinone is a very ancient breed (it is believed to be one of the oldest gun dogs in existence), it is not known exactly what the origins of the breed are; there are many different theories. Some of these claim that the Spinone could have originated in Italy, France, Spain, Russia, Greece, or Celtic Ireland. Some people familiar with the history of the breed claim that
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
