HALO I: Photometric continuum reverberation mapping of Fairall 9

Amit Kumar Mandal, Francisco Pozo Nuñez, Vikram Kumar Jaiswal +23

We investigate the origin of inter-band continuum time delays in active galactic nuclei (AGNs) to study the structure and properties of their accretion disks. We aim to measure the…

Distance to the Globular Cluster M 3 from the Infrared Surface Brightness Technique applied to RR Lyrae stars

Bartłomiej Zgirski, Wolfgang Gieren, Grzegorz Pietrzyński +10

The Infrared Surface Brightness (IRSB) technique is a specific application of the Baade-Wesselink method. Given a proper calibration, well covered optical and near-infrared photome…

Multiplicity of Galactic Cepheids from long-baseline interferometry V. High-accuracy orbital parallax and mass of SU Cygni

A. Gallenne, N. R. Evans, P. Kervella +23

Cepheid masses are particularly necessary to help solving the mass discrepancy, while independent distance determinations provide crucial test of the period-luminosity relation and…

The Infrared Surface Brightness technique applied to RR Lyrae stars from the solar neighborhood

Bartłomiej Zgirski, Wolfgang Gieren, Grzegorz Pietrzyński +9

The Baade-Wesselink method allows us to estimate distances to individual pulsating stars. Accurate geometric parallaxes obtained by the Gaia mission serve us in the calibration of…

The Orbit and Mass of the Cepheid AW Per

Nancy Remage Evans, Alexandre Gallenne, Pierre Kervella +17

The Cepheid AW Per is a component in a multiple system with a long period orbit. The radial velocities of Griffin (2016) cover the 38 year orbit well. An extensive program of inter…

Cepheids with giant companions. II. Spectroscopic confirmation of nine new double-lined binary systems composed of two Cepheids

Bogumił Pilecki, Ian B. Thompson, Felipe Espinoza-Arancibia +13

Binary Cepheids with giant companions are crucial for studying the physical properties of Cepheid variables, providing the best means to measure their masses. Systems composed of t…
