| Spectrum (VSSP J061947.07+170350.7 vs. RCB star V381 Lac) | |
 |
| Remarks | We obtained the low-resolution spectrum using the Alpy 600 spectrograph attached to a 0.6-m f/8 Ritchey-Chretien telescope. The spectrum shows significant cyanide molecular (CN) absorption lines. These features suggest it is a carbon star. We think it’s most likely a RCB star.
J-K=3.83. |
