Enrico Barausse. Binary pulsar test of LV

[Maxim Khlopov]

On 8.11.2013 Enrico Barausse (IAP, Paris, France) gave a talk
"Constraints on Lorentz violation in gravity from binary pulsars"
The record of videoconference with this VIA lecture can be found in Previous -> Lectures
The following questions and comments were put in discussion:
Houri Ziaeepour: How physically do you define the preferred frame?

Houri Ziaeepour: can you add cosmological constraint to these results?

Sergei Kopeikin: What kind of theories can violate Lorentz invariance in gravity?

Houri Ziaeepour: Apparently Horava model can explain acceleration of the universe. Does your calculation be used by next DE surveys?

Houri Ziaeepour: If it is a scalar tensor, it should be adaptable for DE

Shantanu: this is a naive question. do you still get dipole gravitational radiation if there is violation of strong equivalence principle if neutron stars in the binary have the same masses? I also don't remember if the masses of the Hulse-Taylor pulsar are different.

Shantanu: I meant and neutron stars have the same masses


Houri Ziaeepour: You are very right. Usually people forget strong gravitational field
