- A-type main-sequence star (Wikipedia)
An A-type main-sequence star (AV) or A dwarf star is a main-sequence (hydrogen burning) star of spectral type A and luminosity class V (five). These stars have spectra defined by strong hydrogen Balmer absorption lines. They measure between 1.4 and 2.1 solar masses (M☉) and have surface temperatures between 7,600 and 10,000 K. Bright and nearby examples are Altair (A7), Sirius A (A1), and Vega (A0). A-type stars do not have convective zones and thus are not expected to harbor magnetic dynamos. As a consequence, because they do not have strong stellar winds, they lack a means to generate X-ray emissions.
- Interactivist — Ben Morea — Garbage Guerrilla (16beaver.org)
In the late 1960s, Ben Morea was the notorious leader of an unsavory Lower East Side anarchist collective called Up Against the Wall, Motherfucker. As a young historian who studies that period, I’d spent almost three years trying to locate him. All the leads I’d followed went nowhere. It was as if Morea had vanished, every bit as thoroughly as a jet contrail.
