Abstract:
We report new Spitzer 24µm photometry of 76 main-sequence A-type
stars. We combine these results with previously reported Spitzer
24µm data and 24 and 25µm photometry from the Infrared Space
Observatory and the Infrared Astronomy Satellite. The result is a
sample of 266 stars with mass close to 2.5MSun all detected to at
least the ∼7σ level relative to their photospheric emission.

Note (1): Alphabetical and numerical order.
Note (2): Flag on Name, defined as follows:
a = spectroscopic binary;
b = visible double;
c = Algol-type;
d = λ Boo-type;
e = ζ Lep;
f = β Pic;
g = HR 4796A;
h = Vega;
j = Fomalhaut.
Note (3): Normalized ratio of 24µm flux density to expected photospheric
flux density.
Note (4): Reference for non-SIMBAD SpType, defined as follows:
a = Gray et al. (2004, NStars Spectra (Booue: Appalachian State Univ.
Dark Star Obs.));
b = Hauck & North (1993A&A...269..403H 1993A&A...269..403H).
Note (5): A "a" indicates that a value of 6mas was used in calculating
luminosity, because it is consistent with the measured value and
more in line with the moving group membership.
