Lambda Scorpii

Lambda Scorpii (λ Sco, λ Scorpii) is a blue star and the second brightest star system in the constellation Scorpius, and one of the brightest stars in the nighttime sky. It has the Bayer designation λ despite being the second brightest in its constellation. It has the traditional name Shaula, which comes from the Arabic الشولاء al-šawlā´ meaning the raised [tail], as it is found in the tail of the scorpion (Scorpius). It is known as Wei Xiu Ba 尾宿八 (the Eighth Star of the Tail) in Chinese.

Properties

Lambda Scorpii is located some 570 light years away from Earth. Spectroscopic and interferometric observations have shown that A is actually a triple system consisting of two B-type stars and a pre–main sequence star. The primary star is a beta Cephei variable star with rapid brightness changes of about a hundredth of a magnitude. The pre–main sequence star has an orbital period of 6 days and the B companion has a period of 1053 days. The three stars lie in the same orbital plane, strongly suggesting that they were formed at the same time. The masses of the primary, pre–main sequence star and the B companion are 14.5, 2.0 and 10.6 solar masses, respectively. The age of the system is estimated to be in the range 10–13 million years.

I Remember

by: Shiloh

Waking up from the shock, still dying from the night before
So mad I can't speak, but I keep coming back for more
Did you see me there (looking back at you), did you even care?
All the things you said to me, every lie that I believed
I can't erase the memory, I remember
Cut so deep I can't forget, loving you is my regret
I thought that I was over it, but I remember (I remember)
I wanna shut it all out, I wish that this was all a dream (a distant memory)
I try so hard to forget but it keeps coming back to me (it's coming back to me)
I should leave I know (but I keep looking back) but I can't let go
All the things you said to me, every lie that I believed
I can't erase the memory, I remember
Cut so deep I can't forget, loving you is my regret
I thought that I was over it, but I remember (I remember)
I should've known you'd take it all away, shoulda known you'd break my heart again
I should just forget it all but I remember
All the things you said to me, every lie that I believed
I can't erase the memory, I remember
Cut so deep I can't forget, loving you is my regret
