Abstract:
We study the near-infrared properties of 690 Mira candidates in the
central region of the Large Magellanic Cloud, based on time-series
observations at JHKs. We use densely sampled I-band observations from
the OGLE project to generate template light curves in the near-infrared
and derive robust mean magnitudes at those wavelengths. We obtain
near-infrared Period-Luminosity relations for oxygen-rich Miras with a
scatter as low as 0.12 mag at Ks. We study the Period-Luminosity-Color
relations and the color excesses of carbon-rich Miras, which show
evidence for a substantially different reddening law.
Description:
This study used I-band measurements of Miras by OGLE-III (Soszynski et al.
2009, J/AcA/59/239) and JHKs observations from the LMC Near-infrared
Synoptic Survey (LMCNISS; Macri et al. 2015, J/AJ/149/117). LMCNISS
observed the central region of the LMC in JHKs using the CPAPIR camera
at the CTIO 1.5 m telescope.
The data products from this survey include observations for 690 Miras.
681, 679, and 676 variables have measurements in JHKs, respectively,
with 668 observed in all three bands. A total of 84852 individual
photometric measurements are available, which can be separated into
three broad groups based on the observation dates: 2006 November,
2007 January, and 2007 November.
