Limited association between HRR gene alterations and HRD in molecular tumor board cancer samples: Who should be tested for HRD? [PDF]
Int J CancerWhat's new? Currently, no published data on homologous recombination deficiency (HRD) testing in the setting of molecular tumor boards exist. This study in a cohort of 237 patients encompassing 24 different tumor entities assessed by a molecular tumor board shows that inactivating alterations of BRCA1/2 are not always associated with an elevated ...

Metallicities of Classical Cepheids in the Inner Galactic Disk
The Astrophysical Journal, 2023 Metallicity gradients refer to the sloped radial profiles of the metallicities of gas and stars and are commonly seen in disk galaxies. A well-defined metallicity gradient of the Galactic disk is observed particularly well with classical Cepheids, which ...

How rotation affects masses and ages of classical Cepheids
EPJ Web of Conferences, 2017 Classical Cepheid variable stars are both sensitive astrophysical laboratories and accurate cosmic distance tracers. We have recently investigated how the evolutionary effects of rotation impact the properties of these important stars and here provide an

M33 Cepheids from CFHT/MegaCam Survey
The Astronomical Journal, 2022 In this paper we analyze Sloan g, r, i archival imaging data of M33 taken by Hartman et al. using MegaCam at the Canada–France–Hawaii Telescope. To determine the distance to the M33 galaxy, we performed several analytical steps to identify its Cepheid ...

Period–Luminosity Relations for Galactic Classical Cepheids in the Sloan Bands
The Astrophysical Journal, 2023 We present the first period–luminosity (PL) and period–Wesenheit (PW) relations in the Sloan–Pan-STARRS g _P _1 r _P _1 i _P _1 bands for classical fundamental-mode Cepheids in the Milky Way.

Nonthermal X-Rays from Pulsation-driven Shocks in Cepheids
The Astrophysical Journal, 2023 Rapid X-ray phase-dependent flux enhancement in the archetype classical Cepheid star δ Cep was observed by XMM-Newton and Chandra. We jointly analyze thermal and nonthermal components of the time-resolved X-ray spectra prior to, during, and after the ...
