Description We propose to measure the thermal CO lines J = 14-13 and J =
15-14 in the circumstellar envelopes (CSEs) of 2 of the brightest
red supergiant (RSG) stars at far-infrared wavelengths in the Large
Magellanic Cloud (LMC) - WOH G64 and IRAS 05280-6910. CO
lines are useful for measuring molecular gas, which dominates
stellar winds from low-temperature stars, such as RSGs. The
scientific objectives are as follows: (1) What gas mass-loss rates
do LMC RSG stars experience? Mass lost from RSGs consists
mainly of molecular gas, so measurements of the gas mass-loss rate
are crucial. (2) Of particular interest is the influence of low
metallicities, so we will compare the gas-to-dust ratios of evolved
stars in the LMC (half of the solar metallicity) and those in the
Galaxy. (3) Finally, our measurements will help us understand
whether or not RSGs play a key role in the life-cycle of matter
within galaxies (e.g., as dust and gas injectors).

Mission Description Herschel was launched on 14 May 2009! It is the fourth 'cornerstone' mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 µm range, bridging the gap between earlier infrared space missions and groundbased facilities.
