Objective To understand the behavior of the rotation of
intermediate mass evolved stars, such as F, G
and K.
A comparative study of the rotation of binary
and single evolved stars.
An Analysis of the infrared emission in binary
and single evolved.

Reference Data (lists of stars used in this work)
VizieR online Data Catalog: RV and vsini of evolveld
stars (de Medeiros+, 1999).
A catalog of rotational and radial velocities for evolved
stars II and Ib supergiants stars (de Medeiros+, 2002).
A catalog of rotational and radial velocities for evolved
stars: RV and vsini of southern stars (de Medeiros+,
2014)
Post annotation Extended Hipparcos Compilation

Luminosity Class and Spectral Type
Luminosity class are organized as follows:
Ib (supergiants)
II (bright giant)
Binary and Single
Taking the following data: parallax; distance (parsecs),
absoluta magnitude, log , log
e etc.

Infrared (IRAS)
Method applied by Waters et al. (1987), to normal stars:
12 = 0.05 + 3.13 1.26 2 + 0.29 3 + 0.16 4
From of magnitudes 12, 25 e 60 m, according to
Oudmaijer et al (1992)
= 2.5[0.00]
Flux density in Jy
41.04; 90.49 e 1.57
