Experimental Gravity and Pulsar Astrophysics with PSR B1534+12

PSR B1534+12 has proven to be a valuable high-precision laboratory for gravitational physics in the "strong-field" regime. The PUPPI backend provides even greater opportunities for substantial improvements in relativistic-parameter precision, significant measurement of relativistic precession of the pulsar's spin axis, and additional ventures in pulsar astrophysics as discussed in the attached proposal. We request 1) six 90-minute epochs (approximately LST 1430-1600) over the course of the next observing year, and 2) a campaign of 14 consecutive observing days (LST 1345-1700) plus one track (LST 1800-2045) of the polarization calibrator PSR B1929+10, preferably to be scheduled between June and August 2013. Outreach Abstract: Solicitamos a observar PSR B1534+12, un pulsar en orbita con una otra estrella de neutrones. Este tipo de sistema orbital es muy util para investigaciones de la gravitaction en ambientes extremos. Estudiaremos efectos que son debido a la gravedad fuerte para hacer pruebas a la teoria de la relatividad general con precision alta. Tambien investigaremos otras temas dentro la astrofisica de pulsars, como: la historia de la sistema orbital, material electronico en el espacio interestelar, la distancia del pulsar, propiedades de polarizacion de la senal de radio, y el ambiente magnetico del pulsar. Mas informacion se presenta en la propuesta tecnica adjunta.

Remote Observing Request

Observer will travel to AO X Remote Observing In Absentia (instructions to operator)

Section I I - Time Request
The following times are in LST. For these observations night-time is not needed.

Begin ­ End Interval­Interval 1430 ­ 1600 1345 ­ 1700 1800 ­ 2045 ­

Days Needed at This Interval 3 14 1

Time Constraints (Must Be Justified in the Prop osal Text) We request three 90-minute sessions (LST 1430-1600) and a campaign session of 14 consecutive days (LST 1435-1700) of PSR B1534+12 during the first semester. We prefer that the 90-minute sessions be evenly spaced (i.e. about 50 days apart), and that the campaign session takes place between July-August 2013. We also request one track of PSR 1929+10 (LST 1800-2045) during one of the 14 campaign days.

Days Needed at This Interval 3

Time Constraints (Must Be Justified in the Prop osal Text) We request three 90-minute observing sessions of PSR B1534+12 during the second observing semester. As with the first semester, we prefer that each 90-minute session be evenly distributed (i.e. about 50 days between each 90-minute session).
