Abstract (from CDS):

We use high-resolution infrared spectroscopy to investigate the 2001 report by Gatewood and colleagues that ρ CrB's candidate extrasolar-planet companion is really a low-mass star with mass 0.14±0.05 M. We do not detect evidence of such a companion; the upper bounds on the (companion-to-primary) flux ratio at 1.6 µm are less than 0.0024 and 0.005 at the 90% and 99% confidence levels, respectively. Using the H-band mass-luminosity relationship calculated by Baraffe and colleagues, the corresponding upper limits on the companion mass are 0.11 and 0.15 M. Our results indicate that the infrared spectroscopic technique can detect companions in binaries with flux ratios as low as 0.01 to 0.02.
