IP Catalog Update No. 4
The IP Catalog Version 2011a, released
on 2011 Jan 5, contains the folloing changes compared with
Version 2009a.
New Candidate IPs (9 objects)
- IGR J15529-5029 is
a poorly studied INTEGRAL source which could be a CV or
an X-ray binary.
- IGR J16547-1916 is
an INTEGRAL source identified with an optical counterpart
with a magnetic CV-like spectrum, with a 549+/-15 s period seen in
the optical.
- AX J1740.2-2903
(=2XMM J174016.0-290337) is an INTEGRAL source identified
with an optical counterpart with a magnetic CV-like spectrum, with
a 623 s period seen in the X-rays and in the optical. Therefore,
this is a good IP candidate, although some questions remain due to
its X-ray spectrum which is unusual for an IP.
- AX J194939+2631 is an ASCA
Galactic Plane survey source which has been identified with a CV without
a strong He II 4686 line. It may be a low accretion rate IP.
- Swift J2138.8+5544 is a
probable IP based on a CV-like optical spectrum and a 990 s X-ray
period.
- Of the 6 additional INTEGRAL sources have been identified as CVs
by Masetti et al 2010,
one is IGR J16547-1916 (see
above). I'm classifying
IGR J04571+4527,
1RXS J080114.6-462324,
IGR J12123-5802, and
1RXS J211336.1+542226
as "possible" IPs, but ignoring IGR J19552+0044 which
looks like a polar to me, from the optical spectrum.
Changes in Confidence Level (6 objects)
- V2069 Cyg has been
"confirmed" as an IP with the detection of the
spin period (743.2s) in the XMM-Newton and RXTE data.
- AX J1700.1-4157 has been upgraded
to "probable;" because of the faint IR counterpart and the
presence of the 6.7 keV line.
- AX J1740.1-2847 has been upgraded
to "probable;" because of the faint IR counterpart.
- AX J1820.5-1434 has been demoted
to "doubtful;" because of the large spin-down.
- IGR J18173-2509 has been upgraded
to "probable" following the detection of the 830.7 s X-ray
period.
- SDSS J233325.92+152222.1
has been "confirmed" as an IP with the detection
of the spin period (42 min) in the XMM-Newton data.
