Open-cluster density profiles derived using a kernel estimator [PDF]
, 2016 Surface and spatial radial density profiles in open clusters are derived using a kernel estimator method. Formulae are obtained for the contribution of every star into the spatial density profile.

STELLAR INVESTIGATION IN THE OPEN CLUSTER OF POLARIS
Odessa Astronomical Publications, 2008 We present the results of our analysis of high-resolution spectroscopic observations of Cepheid α UMi (Polaris A), and main-sequence type stars Polaris B, and HD 5914, an optical companion and a member of Polaris open cluster.

A Machine-learning-based Investigation of the Open Cluster M67
Astrophysical Journal, 2018 In this paper, we use a machine-learning method, random forest (RF), to identify reliable members of the old (4 Gyr) open cluster M67 based on the high-precision astrometry and photometry taken from the second Gaia data release (Gaia-DR2).

A revised moving cluster distance to the Pleiades open cluster [PDF]
, 2016 Aims: We provide a new distance estimate for the Pleiades based on the moving cluster method, which will be useful to further discuss the so-called Pleiades distance controversy and compare it with the very precise parallaxes from the Gaia space mission.

antiSMASH 6.0: improving cluster detection and comparison capabilities
Nucleic Acids Res., 2021 Many microorganisms produce natural products that form the basis of antimicrobials, antivirals, and other drugs. Genome mining is routinely used to complement screening-based workflows to discover novel natural products.

SS Lac in Open Cluster NGC 7209 [PDF]
Journal of Astronomy and Space Sciences, 1997 We present IUE observations in far ultraviolet region for SS Lac in open cluster NGC 7209. The IUE short wavelength spectrum and long wavelength spectrum were merged to produce an energy distribution curve between 1200A and 3200A.

WIYN OPEN CLUSTER STUDY. XXXII. STELLAR RADIAL VELOCITIES IN THE OLD OPEN CLUSTER NGC 188 [PDF]
, 2015 We present the results of our ongoing radial-velocity (RV) survey of the old (7 Gyr) open cluster NGC 188. Our WIYN 3.5 m data set spans a time baseline of 11 years, a magnitude range of 12 ⩽ V ⩽ 16.5 (1.18–0.94 M☉), and a 1° diameter region on the sky ...

STELLAR RADIAL VELOCITIES IN THE OLD OPEN CLUSTER M67 (NGC 2682). I. MEMBERSHIPS, BINARIES, AND KINEMATICS [PDF]
, 2015 We present results from 13776 radial-velocity (RV) measurements of 1278 candidate members of the old (4 Gyr) open cluster M67 (NGC 2682). The measurements are the results of a long-term survey that includes data from seven telescopes with observations ...
