Chemical Components: Mostly hydrogen, then helium. Since the star is a class
M, its spectrum is expected to have strong absorption lines of helium and TiO. TiO stands
for titanium oxide and it is very common to find TiO in cooler stars such as Antares.
Location: RA = 16h 29m 24.4s, Dec = -26° 25' 55"
