(Oxford Academic, 2012-05)The parameters for the newly discovered open cluster Alessi 95 are established on the basis of available photometric and spectroscopic data, in conjunction with new observations. Colour excesses for spectroscopically ...
-
(American Astronomical SocietyIOP Publishing, 2012-07-10)New X-ray (XMM-Newton) and JHK[subscript s] (Observatoire du Mont-Megantic) observations for members of the star cluster Alessi 95, which Turner et al. discovered hosts the classical Cepheid SU Cas, were used in tandem ...
-
(Oxford Academic, 2012-04)Preliminary constraints are placed on a cluster of young stellar objects (J2000 02:54:31.4 +69:20:32.5) discovered in the field of the classical Cepheid SU Cas. The Wide-field Infrared Survey Explorer (WISE) 3.4-, 4.6-, ...
-
(American Astronomical Society, 1989-12)Reddening line parameters in the UBV system have been derived for early-type stars in six restricted (2[degrees symbol]-3[degrees symbol] radius) Milky Way fields associated with open clusters and/or associations. The ...
-
(Oxford University Press, 2016-02-01)Multicolour photometry of the stellar populations in five fields in the third Galactic quadrant centred on the clusters NGC 2215, NGC 2354, Haffner 22, Ruprecht 11, and ESO489 SC01 is interpreted in terms of a warped and ...
-
Concerning the classical Cepheid VI[subscript C] Wesenheit function's strong metallicity dependence (IOP Publishing, 2011-11-10)Evidence is presented which supports findings that the classical Cepheid VIC period Wesenheit function is relatively insensitive to metallicity. The viability of a recently advocated strong metallicity dependence ...
-
(EDP Sciences, 2016-10)Near-infrared color-excess and extinction ratios are essential for establishing the cosmic distance scale and probing the Galaxy, particularly when analyzing targets attenuated by significant dust. A robust determination ...
-
(IOP Publishing Limited, 2012-03-20)New and existing CORAVEL, UBVJHKs, HST, HIP/Tycho, ARO, KPNO, and DAO observations imply that the fundamental Cepheid calibrator ζ Gem is a cluster member. The following parameters were inferred for ζ ...
-
(EDP Sciences, 2013-07)A new X-ray, UBVRIc, and JHKs study of the young cluster Westerlund 2 was undertaken to resolve discrepancies tied to the cluster’s distance. Existing spectroscopic observations for ...
-
(EDP Sciences, 2014-12)This study helps increase awareness of the pernicious effects of photometric contamination (crowding/blending), since it can propagate an undesirable systematic offset into the cosmic distance scale. The latest Galactic ...
-
(American Astronomical Society, 1986-07)New photoelectric UBVphotometry is presented for stars in NGC 6087, the cluster containing the 9[d over dot]75 Cepheid S Normae. The data are used with published photoelectric observations for cluster stars to redetermine ...
-
(American Astronomical Society, 1992-09)New photoelectric UBV photometry of 27 stars and spectroscopic observations of 12 stars are presented for NGC 129, the cluster containing the 8[d over dot]00 Cepheid DL Cas. The photometry is used to restandardize previously ...
-
(American Astronomical Society, 1992-11)New photoelectric UBV photometry of 45 stars and spectroscopic observations of 24 stars are presented for NGC 1647, the cluster associated with the 3[d with dot below]15 Cepheid SZ Tauri. The resulting photometry, spectral ...

Galactic clusters with associated Cepheid variables. IV. C2128+488 (Anon. Platais) and V1726 Cygni (American Astronomical Society, 1994-05)New photoelectric UBV photometry of 32 stars, photographic UBV photometry of 120 stars, and spectroscopic observations of 8 stars are presented for C 2128+488 (Anon. Platais), the cluster associated with the 4[d over dot]237 ...
-
(American Astronomical Society, 1997-06)Photoelectric and CCD photometry (to a limit of V=17.0) is presented for 61 and 243 stars, respectively--a total of 279 individual stars--in and about IC 1590, a young galactic cluster embedded in the nebulosity of NGC ...
-
(EDP Sciences, 2014-01)Context. Fundamental parameters characterizing the end-state of intermediate-mass stars may be constrained by discovering planetary nebulae (PNe) in open clusters (OCs). Cluster membership may be exploited to establish the ...
-
(EDP Sciences, 1986-10)A distance of 2.5 [plus or minus] 0.2 kpc is derived for the dark globule Lynds 810 using photometric data for foreground stars and star counts. It is argued that this globule is likely to belong to the Vul OB1 complex. ...
-
(IOP Publishing Limited, 2012-03-10)New and existing UBVJHKs, spectroscopic, NOMAD, Hubble Space Telescope, and revised Hipparcos observations are employed to determine properties for δ Cep and its host star cluster. The multi-faceted approach ...
-
(IOP Publishing, 2011-11-10)The putative association between the 10.d 8 classical Cepheid TW Nor and the open cluster Lyngå 6 has generated considerable debate in the literature. New JHKs photometry in tandem with existing ...
-
(American Astronomical Society, 1988-11)The Baade-Wesselink method has been reapplied to existing photometric and radial-velocity measures for the classical Cepheid [delta] Cephei, but a different approach to the analysis was adopted in which spectrophotometric ...
