General Description

The aime of this project is to determine  the  stellar  projected rotational
 velocity and the surface chemical abundances of a  statistically  significant number
 of   hot  horizontal branch (HB)  stars in  the globular cluster NGC~6752. Using
 the multiobject capabilities and the resolution of UVES+FLAMES, we  can reveal the
 presence of anomalous fast HB rotators and perform a detailed study of stellar rotation
 as a function of other physical properties (position of the star on the HB, surface
 chemical abundances). 

In this way, we propose to shed more light on the origin of fast rotation among
 HB
stars and,  in   particular, to  clarify  any  connection   with
dynamical or evolutionary  effects.

Six stars, standars of stellar rotation are also included in the proposal.

Waiver Requests

A waiver request to ask for exposure times longer than 1 hour, including
 overheads, for the globular cluster stars was aproved for this programme.

Critical Observing Condition Constraints

There are no additional critical observing condition constraints appart
 from the seeing and
airmass conditions indicated in the OBs and the proposal.

Time-Critical Aspects

There are no particular time-critical aspects for this programme.
