Abstract:
From a number of known post common envelopes binaries (PCEB) only a
handful have yet been observed at near-infrared (NIR) wavelengths, and
even fewer have modeled NIR light curves. At shorter wavelengths one
has access to the cooler and larger components of these systems and
has a chance to detect emission from its faint and heavily irradiated
atmospheres.
By modeling NIR light curves of PCEBs, we intend to constrain their
system parameters and study the properties of the system components.
Description:
Near-infrared time resolved photometric observations of KV Vel and TW
Crv. KV Vel was observed quasi-simultaneously in JHK bands while TW
Crv was observed on the H and K bands. Table contains the flux
calibrated photometric measurements for each object on each band and
consists of phase, flux and flux error.
