Eccentric Double White Dwarfs as Lisa Sources in Globular Clusters
We consider the formation of double white dwarfs (DWDs) through dynamical interactions in globular clusters. Such interactions can give rise to eccentric DWDs, in contrast to the exclusively circular population expected to form in the Galactic disk. We show that for a 5 yr Laser Interferometer Space Antenna (LISA) mission and distances as far as the Large Magellanic Cloud, multiple harmonics fr...
متن کاملProbing white dwarf interiors with LISA: periastron precession in eccentric double white dwarfs.
In globular clusters, dynamical interactions give rise to a population of eccentric double white dwarfs detectable by the Laser Interferometer Space Antenna (LISA) up to the Large Magellanic Cloud. In this Letter, we explore the detectability of periastron precession in these systems with LISA. Unlike previous investigations, we consider contributions due to tidal and rotational distortions of ...
متن کاملThe Lisa Gravitational Wave Foreground: a Study of Double White Dwarfs
Compact object binaries, mostly double white dwarfs, are expected to be a source of confusion-limited noise for the gravitational wave observatory LISA. In a specific frequency range, this ‘foregound noise’ is predicted to rise above the instrumental noise sources and hinder the detection of other types of signals, e.g., gravitational waves arising from stellar mass objects inspiraling into mas...
متن کاملMass Transfer between Double White Dwarfs
Three periodically variable stars have recently been discovered (V407 Vul, P = 9.5 min; ES Cet, P = 10.3 min; RX J0806.3+1527, P = 5.3 min) with properties that suggest that their photometric periods are also their orbital periods, making them the most compact binary stars known. If true, this might indicate that close, detached, double white dwarfs are able to survive the onset of mass transfe...
متن کاملModelling the formation of double white dwarfs
We investigate the formation of the ten double-lined double white dwarfs that have been observed so far. A detailed stellar evolution code is used to calculate grids of single-star and binary models and we use these to reconstruct possible evolutionary scenarios. We apply various criteria to select the acceptable solutions from these scenarios. We confirm the conclusion of Nelemans et al. (2000...
