What does Sirius a look like?
Sirius A has a spectral type of A1V. So it has a colour of white to white blue.
What is the spectral class of Sirius?
Sirius is classified as an A-type main sequence star. It is specifically categorized as an A1V star, with a surface temperature of about 9,940 K.
Why would the star Sirius find that its spectral lines are blue shifted?
The spectral lines of Sirius are blueshifted because the star is moving more or less toward us.
Where is the Sirius star on h-r diagram?
Sirius is a binary star. Sirius A has a spectral type of A1V and will appear on the HR in the top left corner. Sirius B has a spectral type of DA2 and will appear on the HR in the bottom left corner as a white dwarf.

What is spectral class?
Spectral class is a classification system for stars based on their temperature and spectral characteristics. It categorizes stars into different groups, such as O, B, A, F, G, K, and M, with O being the hottest and M being the coolest. Spectral class is indicated by a letter, with additional subtype information denoted by a number.
Of the spectral classes the highest temperature class is designated as what?
The O spectral class is the highest temperature class. Stars in this class are extremely hot and blue in color, with surface temperatures exceeding 30,000 K.
