  Epsilon Eridani is a nearby, young Sun-like star that hosts a ring of cool
debris analogous to the solar system's Edgeworth-Kuiper belt. Early
observations at (sub-)mm wavelengths gave tentative evidence of the presence of
inhomogeneities in the ring, which have been ascribed to the effect of a
putative low eccentricity planet, orbiting close to the ring. The existence of
these structures have been recently challenged by high resolution
interferometric millimeter observations. Here we present the deepest
single-dish image of Epsilon Eridani at millimeter wavelengths, obtained with
the Large Millimeter Telescope Alfonso Serrano (LMT). The main goal of these
LMT observations is to confirm (or refute) the presence of non-axisymmetric
structure in the disk. The dusty ring is detected for the first time along its
full projected elliptical shape. The radial extent of the ring is not spatially
resolved and shows no evidence, to within the uncertainties, of dust density
enhancements. Additional features of the 1.1 mm map are: (i) the presence of
significant flux in the gap between the ring and the star, probably providing
the first exo-solar evidence of Poynting-Robertson drag, (ii) an unambiguous
detection of emission at the stellar position with a flux significantly above
that expected from Epsilon Eridani's photosphere, and (iii) the identification
of numerous unresolved sources which could correspond to background dusty
star-forming galaxies.
