Sun in 8th house.

So, lets see what Sun can do in 8th house without any conjunction or aspect from any other planet. 1st lets see what these 2 things represent -

Sun represents King, Government, Father, Authority, Career, Top Positions, Ego, Self Esteem etc.

8th house is house of secrecy, occult knowledge, death, transformation, death and re-birth, In laws family, joint wealth with spouse etc.

Sun is Confidence and 8th house is sudden ups and downs in life. So, when Sun is in 8th house, it shows that person's confidence will get a beating in early life due to sudden changes and ups/downs in life. They will meet such people or face such events which will naturally hurt their ego. Again, nothing can keep the Sun away from shinning all the time. More changes and challenges they face in life, more confident they become.

They can be in any career related with research, secrets and taxes. They can get into ego conflicts in matters of marriage and in-laws. This is something they need to work. 

But this is again a placement which will give better result in 30s after person has seen through all the changes of life. 

Thanks,
