A previously derived photometric parallax of 10.10  ±  0.20 mas, d = 99  ±  2 pc, is confirmed for Polaris by a spectroscopic parallax derived using line ratios in high dispersion spectra for the Cepheid. The resulting estimates for the mean luminosity of 〈MV〉 = −3.07  ±  0.01 s.e., average effective temperature of 〈Teff〉 = 6025  ±  1 K s.e., and intrinsic color of (〈B〉  −  〈V〉)0 = +0.56  ±  0.01 s.e., which match values obtained previously from the photometric parallax for a space reddening of…

THE PULSATION MODE AND DISTANCE OF THE CEPHEID FF AQUILAE
The determination of pulsation mode and distance for field Cepheids is a complicated problem best resolved by a luminosity estimate. For illustration a technique based on spectroscopic luminosity
Revisiting the fundamental properties of the Cepheid Polaris using detailed stellar evolution models
Polaris the Cepheid has been observed for centuries, presenting surprises and changing our view of Cepheids and stellar astrophysics, in general. Specifically, understanding Polaris helps anchor the
Evolutionary status of Polaris
Hydrodynamic models of short--period Cepheids were computed to determine the pulsation period as a function of evolutionary time during the first and third crossings of the instability strip. The
Homing in on Polaris: A 7 M⊙ first-overtone Cepheid entering the instability strip for the first time
A recently presented HST/FGS parallax measurement of the Polaris system has been interpreted as evidence for the Cepheid Polaris Aa to be pulsating in the second overtone. An age discrepancy between
HD 344787: a true Polaris analogue?
Context. Classical Cepheids (DCEPs) are the most important primary indicators for the extragalactic distance scale, but they are also important objects in their own right, allowing us to place
Hubble Space Telescope Trigonometric Parallax of Polaris B, Companion of the Nearest Cepheid
Polaris, the nearest and brightest Cepheid, is a potential anchor point for the Leavitt period–luminosity relation. However, its distance is a matter of contention, with recent advocacy for a
The Cepheid period–luminosity–metallicity relation based on Gaia DR2 data
Aims. We use parallax data from the Gaia second data release (GDR2), combined with parallax data based on HIPPARCOS and HST data, to derive the period–luminosity–metallicity (PLZ) relation for
The Orbit of the Close Companion of Polaris: Hubble Space Telescope Imaging, 2007 to 2014
As part of a program to determine the dynamical masses of Cepheids, we have imaged the nearest and brightest Cepheid, Polaris, with the Hubble Space Telescope (HST) Wide Field Planetary Camera 2 and
Galactic open cluster Cepheids – a census based on Gaia EDR3
In the Gaia era, the membership analysis and parameter determination of open clusters (OCs) are more accurate. We performed a census of OC’s classical Cepheids based on Gaia Early Data Release 3
The Hipparcos parallax for Polaris
This Letter follows a recent claim that the Hipparcos parallax for Polaris could be too small by 2.5 mas. It examines in detail the Hipparcos epoch astrometric data for Polaris, as well as the
