They
say
that
it
requires
the
complete
renaming
of
only
two
exoplanetary
systems
:
The
planets
around
HW
Virginis
would
be
renamed
HW
Vir
(
AB
)
b
&

;
(

c
,
whereas
those
around
NN
Serpentis
would
be
renamed
NN
Ser
(
AB

b
&

(

)
c
.
In
addition
the
previously
known
single
circumbinary
planets
around
PSR
B1620-26
and
DP
Leonis
can
almost
retain
their
names
(
PSR

and
DP
Leonis
b
)
as
unofficial
informal
forms
of
the
``

designation
where
the
``

is
left
