Well, both of these theories could explain part of the data, but the difficulties were that the star showed no signs of being young, and there was no glow from any of the material that was heated up by the star's light, and you would expect this if the star was young or if there was a collision and a lot of dust was produced.
Ambas as teorias podiam explicar parte dos dados, mas a estrela não mostrava sinais de ser jovem, e não havia o brilho vindo da matéria que seria aquecida pela luz da estrela, e seria de esperar brilho se a estrela fosse jovem ou tivesse havido uma colisão e fosse produzida muita poeira.
