The Cepheid Impostor HD 18391 and its Anonymous Parent Cluster

, 2009
New and existing photometry for the G0 Ia supergiant HD 18391 is analyzed in order to confirm the nature of the variablity previously detected in the star, which lies off the hot edge of the Cepheid instability strip.

Catalog of Integrated-light Star Cluster Light Curves in TESS

The Astronomical Journal, 2023
We present the first integrated-light, TESS-based light curves for star clusters in the Milky Way, Small Magellanic Cloud, and Large Magellanic Cloud. We explore the information encoded in these light curves, with particular emphasis on variability.

The Hubble Space Telescope Extragalactic Distance Scale Key Project. X. The Cepheid Distance to NGC 7331

, 1998
The distance to NGC 7331 has been derived from Cepheid variables observed with HST/WFPC2, as part of the Extragalactic Distance Scale Key Project. Multi-epoch exposures in F555W (V) and F814W (I), with photometry derived independently from DoPHOT and ...

Viability of Self‐Taken Vaginal Swab Samples for RNA‐Based Biomarker Analysis in Cervical Disease

Journal of Medical Virology, Volume 97, Issue 12, December 2025.
ABSTRACT High risk human papillomaviruses (hrHPVs) cause most cervical cancers. Cervical screening programmes aim to identify precancerous disease using detection of hrHPV nucleic acid using clinician‐taken liquid‐based cytology (LBC) samples, or increasingly, self‐taken samples (STSs).

Fundamentalization of Periods for First- and Second-overtone Classical Cepheids

The Astrophysical Journal Letters
Almost half of all classical Cepheids do not pulsate in fundamental mode, and nowadays, the fundamentalization of their higher-mode periods is frequently applied to increase the sample size in astrophysical investigations and allow for comparison with ...

Faint (and bright) variable stars in the satellites of the Milky Way

EPJ Web of Conferences, 2017
I describe two ongoing projects related with variable stars in the satellites of the MilkyWay. In the first project, we are searching for dwarf Cepheid stars (a.k.a δ Scuti and/or SX Phe) in some of the classical dwarf spheroidal galaxies. Our goal is to

Cervical intraepithelial neoplasia progression and regression among women living with HIV in Zambia

HIV Medicine, Volume 26, Issue 12, Page 1939-1949, December 2025.
Abstract Objectives Cervical screening and precancer treatment are less effective in women living with HIV (WLWH) than in women without HIV. We assessed high‐risk human papillomavirus (HR‐HPV) infection and cervical disease progression among screened WLWH in Zambia. Methods Participants underwent visual inspection with acetic acid (VIA), HR‐HPV testing

Systematics in the Cepheid and TRGB Distance Scales: Metallicity Sensitivity of the Wesenheit Leavitt Law

The Astrophysical Journal
Using an updated and significantly augmented sample of Cepheid and tip of the red giant branch (TRGB) distances to 28 nearby spiral and irregular galaxies, covering a wide range of metallicities, we have searched for evidence of a correlation of the zero-

Long‐term risk and predictors of high‐risk human papillomavirus persistence after thermal ablation amongst women living with HIV in West Africa

HIV Medicine, Volume 26, Issue 12, Page 1950-1962, December 2025.
Abstract Introduction Mounting evidence supports the use of thermal ablation in women positively screened with high‐risk Human Papillomaviruses (hrHPV) but limited data are available on the long‐term post‐treatment outcomes in women living with HIV (WLHIV).
