Abstract

A 24 day period for the low-mass X-ray binary GX 13+1 was previously proposed on the basis of 7 years of RXTE ASM observations (Corbet 2003) and it was suggested that this was the orbital period of the system. This would make it the longest orbital period known for an LMXB powered by Roche lobe overflow. We present here the results of: (i) K-band photometry obtained with the SMARTS consortium CTIO 1.3 telescope on 68 nights over a 10 month interval; and (ii) Continued monitoring with the RXTE ASM, analyzed using a semi-weighted power spectrum instead of the data filtering technique employed in Corbet (2003). The 24 day period is confirmed from both the K-band and additional X-ray observations. We compare the relative phasing and amplitudes of the modulation in the two wavebands to investigate the structure of the components in the GX 13+1 system.
