| Abstract: |
We present CRIRES observations of the “normal" carbon star TX Psc in
the K, L and M bands, taken in 2010 and 2013. The spectro-astrometry
shows clear signatures for the presence of a bright blob south of the star
and several photospheric radii away.
The flux ratio between blob and star is between 5% and 10%.
This blob also shows up as an additional absorption component in the
red wings of the CO lines. |
