DOI: 10.1088/1538-3873/ad7405
Abstract: The classical Cepheid KQ Sco is a valuable anchor for the distance scale because of its long pulsation period (28.ͩ7) and evidence implying membership in the open cluster UBC 1558. Analyses tied to Gaia DR3… read more here.

DOI: 10.1093/mnras/staf308
Abstract: The Hubble constant (H0) is a key parameter in cosmology, yet its precise value remains contentious due to discrepancies between early- and late-universe measurement methods, a problem known as the “Hubble tension.” In this study,… read more here.

DOI: 10.1093/mnras/stw2399
Abstract: We present a detailed analysis of the bright Cepheid-type variable star V1154 Cygni using 4 years of continuous observations by the Kepler space telescope. We detected 28 frequencies using standard Fourier transform method.We identified modulation… read more here.

DOI: 10.1093/mnras/sty1280
Abstract: As part of a wider investigation of evolved massive stars in Galactic open clusters, we have spectroscopically identified three candidate classical Cepheids in the little-studied clusters Berkeley 51, Berkeley 55 and NGC 6603. Using new… read more here.
