Properties of the ionized gas in HH 202 – II. Results from echelle spectrophotometry with ultraviolet visual echelle spectrograph ⃰ [PDF]

, 2009
We present results of deep echelle spectrophotometry of the brightest knot of the Herbig–Haro object HH 202 in the Orion Nebula – HH 202-S – using the Ultraviolet Visual Echelle Spectrograph in the spectral range from 3100 to 10 400 Å.

A Comprehensive Study of the Relations between the Properties of Planetary Systems and the Chemical Compositions of Their Host Stars

The Astrophysical Journal
The giant planet–metallicity correlation revealed that planetary formation depends on the stellar properties. There is growing evidence that it is also valid for smaller hot planets, but it is not clear whether elements other than iron also influence the
