IRAS Point Source Identifications (Cat. III/170)
by B. Skiff
IRAS coords lie between this star and DO 11468(K5);
MSX6C shows similar A-band flux for both stars.
eastern of two red stars contributing equally to the IRAS source;
western star = DO 1628: 6 32 51.80 +01 25 37.5 (U), DO type M1.
earlier than type M2/3 but reddened, per MacC email 2005Nov7.
this is a reflection nebula classified in error as type M10?.
MacC notes indicate two stars of type M8, but only one red star is
evident on visible-light and 2MASS images.
nearby HD 56747 probably contributes to IRAS flux.
not a red star: type M5? probably an error per MacC email of 2005Jun27.
The IRAS source is probably not nearby CGCS 1793,
though a poor IRAS position is not excluded.
second red star at 7 38 47.5 -08 45 29 (J2000) contributes to IRAS flux,
however no TiO present per MacC e-mail 2005Jun27.
original type (M6:) revised per MacC re-examination of plates 2005Jul1,
and definitely not a carbon star.
carbon, not type M5:, per MacC re-examination of plates 2005Jul1.
MacC re-examination of plates 2005Jul13 suggests strong CN, but not
obviously a carbon star.
another fainter red star at 8 38 40.84 -41 48 51.1 (U) contributes to the
type for M7 star per MacC e-mail 2006Mar1.
MacC re-examination of plates 2006Apr3: the forbidden emission lines
probably mistaken for TiO bandheads; IR CaII triplet seems to be in emission
