Fornax

The Chemical Furnace. A faint → constellation in the southern sky, representing a chemist's furnace. Its brightest star, Alpha Fornacis, is a double of magnitudes 4.0 and 6.5. Abbreviation: For; genitive: Fornacis.

L. fornax "oven, kiln," related to fornus, furnus "oven," and to formus "warm," from PIE base *ghworm-/*ghwerm- "warm" (cf. Mod./Mid.Pers. garm "warm;" O.Pers./Av. garəma- "hot, warm;" Skt. gharmah "heat;" Gk. thermos "warm;" cf. O.E. wearm; O.H.G., Ger. warm).
Fornax was created and named by Abbé Nicolas Louis de Lacaille (1713-1762) in honor of Antoine Lavoisier, the French chemist, who was guillotined in the French Revolution in 1794. He created it out of several faint stars in the constellation → Eridanus.

Kuré "furnace;" Tabari kalə "furnace," kəlen "ash;" Laki koira; Kurd. kulan, kulandan "to cook;" Laki koira; Kurd. kulan, kulandan "to cook;" related to garm "warm;" cf. Skt. ghar- "to burn;" E. kiln "furnace, oven," from L. culina "cooking stove, kitchen;" PIE root *gwher- "to warm, be warm," → warm.

2) In → asteroseismology, a model that takes the physical properties of a star as input parameters and predicts the star's oscillations. Then, by finding parameters that yield oscillation frequencies (ωnlm) close to those observed, one can infer the properties of the observed star. The quantum numbers n, l, and m must be identified before any meaningful comparison between seismic data and model predictions can be made. That mode identification requires a physical interpretation of the measured frequencies.

forward shock
  تش ِ پیش-سو
