Integral field spectroscopy of HH 262: the spectral atlas
López, R.; García-Lorenzo, B.; Sánchez, S. F.;Gómez, G.; Estalella, R.; Riera, A.. Integral field spectroscopy of HH 262: the spectral atlas. Monthly Notices of the Royal Astronomical Society. 2008, Vol. Volume 391, Issue 3, pp. 1107-1116., p. -2008.
HH 262 is a group of emitting knots displaying an `hour-glass'
morphology in the Hα and [SII] lines, located 3.5 arcmin to the
north-east of the young stellar object L1551-IRS5, in Taurus. We present
new results of the kinematics and physical conditions of HH 262 based on
Integral Field Spectroscopy covering a field of ~1.5 × 3
arcmin<SUP>2</SUP>, which includes all the bright knots in HH 262. These
data show complex kinematics and significant variations in physical
conditions over the mapped region of HH 262 on a spatial scale of <=3
arcsec. A new result derived from the Integral Field Spectroscopy data
is the weakness of the [NII] emission (below detection limit in most of
the mapped region of HH 262), including the brightest central knots. Our
data reinforce the association of HH 262 with the redshifted lobe of the
evolved molecular outflow L1551-IRS5. The interaction of this outflow
with a younger one, powered by L1551 NE, around the position of HH 262
could give rise to the complex morphology and kinematics of HH 262.
