Abstract:
NSV 11154 has been confirmed as a new member of the rare hydrogen-
deficient R Coronae Borealis (RCB) stars based on new photometric and
spectroscopic data. Using new photometry, as well as archival plates
from the Harvard archive, we have constructed the historical
lightcurve of NSV 11154 from 1896 to the present. The lightcurve shows
the sudden, deep, irregularly spaced declines characteristic of RCB
stars.
Description:
The Sonnenberg Plate data, taken by a 40cm astrograph on
blue-sensitive photographic plates (Haussler et al.,
2009IBVS.5890....1H 2009IBVS.5890....1H), were downloaded for use in this study.
The photometric data were downloaded from the NSVS archive.
New BVRcIc photometry has been obtained with the AAVSO Sonoita
Research Observatory (SRO) between 2010 October and 2011 June.
The images were obtained with the 35cm C14 OTA (SRO35) and the
50cm f/4 Newtonian (SRO50).
