Abstract:
We use the AllWISE Data Release to continue our search for Wide-field
Infrared Survey Explorer (WISE)-detected motions. In this paper, we
publish another 27846 motion objects, bringing the total number to
48000 when objects found during our original AllWISE motion survey are
included. We use this list, along with the lists of confirmed
WISE-based motion objects from the recent papers by Luhman (2014,
J/ApJ/781/4) and by Schneider et al. (2016, J/ApJ/817/112), and
candidate motion objects from the recent paper by Gagne et al. (2014,
J/ApJ/783/121), to search for widely separated, common-proper-motion
systems. We identify 1039 such candidate systems. All 48000 objects
are further analyzed using color-color and color-mag plots to provide
possible characterizations prior to spectroscopic follow-up. We
present spectra of 172 of these, supplemented with new spectra of 23
comparison objects from the literature, and provide classifications
and physical interpretations of interesting sources. Highlights
include: (1) the identification of three G/K dwarfs that can be used
as standard candles to study clumpiness and grain size in nearby
molecular clouds because these objects are currently moving behind the
clouds, (2) the confirmation/discovery of several M, L, and T dwarfs
and one white dwarf whose spectrophotometric distance estimates place
them 5-20pc from the Sun, (3) the suggestion that the Na I "D" line be
used as a diagnostic tool for interpreting and classifying metal-poor
late-M and L dwarfs, (4) the recognition of a triple system including
a carbon dwarf and late-M subdwarf, for which model fits of the late-M
subdwarf (giving [Fe/H]~-1.0) provide a measured metallicity for the
carbon star, and (5) a possible 24pc distant K5 dwarf + peculiar red
L5 system with an apparent physical separation of 0.1pc.
Description:
Observations for the spectroscopic follow-up of interesting AllWISE
sources are listed in Table 4.
Optical follow-up was conducted with the Palomar/Double Spectrograph
on the Hale 5m telescope on Palomar Mountain, California, as our
primary optical spectrograph in the northern hemisphere. It was used
during the UT nights of 2014 January 26, February 23/24, April 22,
June 25/26, July 21, September 27, October 24, and November 15 as well
as 2015 June 08, September 07, and December 10. The Boller & Chivens
Spectrograph (BCSpec) on the 2.5m Irenee duPont telescope at Las
Campanas Observatory, Chile, served as our primary optical
spectrograph in the southern hemisphere and was used on the UT nights
of 2014 April 30, May 01-04, and November 16-20. Spectra of 10 objects
were obtained on the UT nights of 2014 July 03-04 and 2015 December
07-10 at the European Southern Observatory (ESO) 3.58m New Technology
Telescope (NTT) at La Silla, Chile. Spectra of seven objects were
obtained on the UT nights of 2014 June 26, 2015 August 13, and 2015
December 05 with the Low Resolution Imaging Spectrometer (LRIS) at the
10m W. M. Keck Observatory on Mauna Kea, Hawaii.
SpeX on the NASA 3m Infrared Telescope Facility (IRTF) on Mauna Kea,
Hawaii, served as our primary near-infrared spectrograph in the
northern hemisphere. The UT dates of observation were 2014 November 11
and 2015 January 27, May 08-09, June 27, July 03-05, and July 20. The
Folded-port Infrared Echellette (FIRE) at the 6.5m Walter Baade
Telescope at Las Campanas Observatory, Chile, served as our primary
near-infrared spectrograph in the southern hemisphere. The UT dates of
observation were 2014 August 07-09, 2015 February 08, and 2015 May 31.
Several sources were also observed with the Near-Infrared Spectrometer
(NIRSPEC) at the 10m W. M. Keck Observatory on Mauna Kea, Hawaii. The
observation dates were UT 2014 April 12 and December 03, and 2015 July
03 and July 11.

Note on table1.dat: 54 of the 10598 confirmed motion objects (0.5% of the total)
were rejected by additional criteria discussed in section 2.1.
Note on table3.dat: Because they were not published in Kirkpatrick et al.
(2014, J/ApJ/783/122), the 16628 re-discovered motion objects found as part
of our previous AllWISE1 survey are listed in table 3.
Note on table8.dat: Detections in the X-ray or ultraviolet were assumed if our
AllWISE object falls within 30" of a 3σ detection from the
Rontgensatelit (ROSAT) or 20" of a 3σ detection in either the far- (FUV)
or near-ultraviolet (NUV) from the Galaxy Evolution Explorer (GALEX), these
radii taking into account the resolution of each survey and the time span
between them and AllWISE. See section 4.3.1.
