[vsnet-chat 2986] RE: [vsnet 2012] EsB365 observations and request

[Sebasti若n Otero <varsao@fullzero.com.ar>]

The L type is asigned to slow pulsating red stars and not to every star with
an uncertain classification. The * symbol is used for them. EsB365 is not
showing signs of eruptive variability and I agree with Brian Skiff in that
maybe it is an SR. But it is not showing any periodicity.
I have a long list of suspected and ex-suspected RCB's and I'm constantly
observing LV TrA, given as RCB: in the GCVS. But you can't  be too confident
in classifications: Taking a look at The 75th Name List of Variable Stars
with the new GCVS designated stars, we can find ZETA PUPPIS, an O5Iaf
supergiant classified as a BY: , when BY's are defined as dwarfs of dKe and
dMe spectral type.

Let's keep on observing and we'll find out.

Sebasti睹 Otero.

Surely there are some more uncertain classifications, EsB365 not being the
only one.
For instance V1860 Sgr is also considered a possible RCB and V803 Cen has
been as well not so long ago.
B-V measures ought to sort most of them out....

Isn't the L* classification meant for those uncertain cases?
