[vsnet-chat 6814] Distance indicators

Dear friends of VSNET,

Hi! My name is Federico Claus, Cls in VSNET code, and I write again to
ask you some help. I was asked to share my knowledge about distance
indicators, such as Cepheids and RR Lyrae, in my astronomy club and I was
wondering if there is any other kind of variable star that can help us to
measure distances in the universe, besides the objects I mentioned before. I
think SNIa do so, but I'm not quite sure. If it's not a problem, can you
give me some references so that I can read and explain it?
I will apreciate your help. Thanks and best regards,

FEDERICO CLAUS
