Studying Hierarchical Triple Galactic Binaries in LISA

ORAL

Abstract

The Laser Interferometer Space Antenna (LISA) is expected to be sensitive to tens of millions of binaries in our galaxy, most of which will constitute a noise source. It is expected that tens of thousands of these binaries will be resolvable by LISA and a substantial fraction of those will be part of hierarchical triple systems. I will discuss modeling these systems for LISA, and determine how well we can estimate the parameters of the outer orbit. Furthermore, I will discuss the potential existence and properties of a ``confusion'' regime of parameters space where the triple system could be mis-identified as an isolated binary leading to biased parameter estimation.
