Gamma Arietis (also called Mesartim) is a stunning, perfectly matched double with both components shining a silvery blue.
Hatzes shows a real star,
Gamma Arietis. It shows a spot where ionized silicon is underabundant, surrounded by a ring of overabundance.
And
Gamma Arietis, Mesartim, is a splendid and easy telescopic double star, magnitudes 4.6 and 4.7, 8" apart.
During more than eight hours the next night Zay recorded only 10 candidates; the lines of six intersected near
Gamma Arietis and four at a pair of points in Triangulum.
But how can one mention Gamma Arietis without talking about it as a double star?
As hauntingly beautiful as I find Gamma Arietis, I like Alpha Piscium even better.
Struve 178, just over the Aries border, is a much fainter clone of Gamma Arietis. I suspect that if you look at Gamma in a 2-inch and [Sigma] 178 in a 10-inch, it will be hard to tell them apart (except for their orientation).
