Beta Canis Majoris (β Canis Majoris, abbreviated Beta CMa, β CMa), also named Mirzam / ˈ m ɜːr z əm /, [13] is a star in the southern constellation of Canis Major, the "Great Dog", located at a distance of about 500 light-years (150 parsecs) from the Sun. [1] In the modern constellation it lies at the position of the dog's front leg.
A peculiar characteristic of this form of the H–R diagram is that the temperatures are plotted from high temperature to low temperature, which aids in comparing this form of the H–R diagram with the observational form. Although the two types of diagrams are similar, astronomers make a sharp distinction between the two.
2. Hypothermia . Hypothermia occurs when the body temperature drops to a dangerously low level. This can happen very quickly in smaller breeds of dogs, puppies, and older dogs.
A simple chart for classifying the main star types using Harvard classification In astronomy , stellar classification is the classification of stars based on their spectral characteristics. Electromagnetic radiation from the star is analyzed by splitting it with a prism or diffraction grating into a spectrum exhibiting the rainbow of colors ...
A cool star, it has a surface temperature of around 2,900 K and a radius 234 times that of the Sun, its distance estimated at 1,444–1,450 light-years from Earth. [68] At the other extreme in size is RX J0720.4-3125 , a neutron star with a radius of around 5 km. [ 69 ] Exceedingly faint, it has an apparent magnitude of 26.6. [ 70 ]

Artistical representation of Canopus. The white color is due to the star having a higher temperature than the Sun. The absorption lines in the spectrum of Canopus shift slightly with a period of 6.9 d. This was first detected in 1906 and the Doppler variations were interpreted as orbital motion. [58]
