On the incidence of \textit{WISE} infrared excess among solar analog,
  twin and sibling stars
  This study presents a search for IR excess in the 3.4, 4.6, 12 and 22 $\mu$m
bands in a sample of 216 targets, composed of solar sibling, twin and analog
stars observed by the \textit{WISE} mission. In general, an infrared excess
suggests the existence of warm dust around a star. We detected 12 $\mu$m and/or
22 $\mu$m excesses at the 3$\sigma$ level of confidence in five solar analog
stars, corresponding to a frequency of 4.1 $\%$ of the entire sample of solar
analogs analyzed, and in one out of 29 solar sibling candidates, confirming
previous studies. The estimation of the dust properties shows that the sources
with infrared excesses possess circumstellar material with temperatures that,
within the uncertainties, are similar to that of the material found in the
asteroid belt in our solar system. No photospheric flux excess was identified
at the W1 (3.4 $\mu$m) and W2 (4.6 $\mu$m) \textit{WISE} bands, indicating
that, in the majority of stars of the present sample, no detectable dust is
generated. Interestingly, among the sixty solar twin stars analyzed in this
work, no \textit{WISE} photospheric flux excess was detected. However, a
null-detection excess does not necessarily indicate the absence of dust around
a star because different causes, including dynamic processes and instrument
limitations, can mask its presence.
