Abstract:
This sample of 370 Mira variables that are likely near the Galactic
center (GC) has been selected from the OGLE and BAaDE surveys based on
their sky coordinates, OGLE classifications, and BAaDE maser-derived
line-of-sight velocities. As the distance to the GC is known to a high
accuracy, this sample is a test bed for reddening and extinction
studies toward the GC and in Mira envelopes. The reddening laws in the
circumstellar environments of our sample and the circumstellar
environments of Large Magellanic Cloud Miras are strikingly similar
despite the different metallicities of the samples. The sample is used
to develop period-magnitude relations for the mid-infrared WISE and
MSX bands.
Description:
Sources taken from the OGLE Mira and BAaDE surveys which are likely to
lie near the center of the Milky Way. Chosen by their line-of-sight
velocity and coordinates.
