Finding the elusive RR Lyrae companions via speckle imaging

R. Salinas, V. Kalari, G. Hajdu +25

Despite their key role in astrophysics, the binary properties of RR Lyrae stars (RRL) remain almost completely unknown since only a single RRL is confirmed as belonging to a binary…

Paving the Road to the Habitable Worlds Observatory with High-Resolution Imaging I: New and Archival Speckle Observations of Potential HWO Target Stars

Zachary D. Hartman, Catherine A. Clark, Michael B. Lund +15

One of the key goals of the Habitable Worlds Observatory (HWO) is to directly image about 25 potentially habitable exoplanets and determine their properties. This challenge will re…

A high fraction of close massive binary stars at low metallicity

H. Sana, T. Shenar, J. Bodensteiner +74

At high metallicity, a majority of massive stars have at least one close stellar companion. The evolution of such binaries is subject to strong interaction processes, heavily impac…

Inside the Iron Curtain: A Long Term Look at the Iron Stars XX Oph and AS 325

Steve B. Howell, Venu M. Kalari, Andy Adamson +1

The Iron Stars XX Oph and AS 325, both binaries consisting of a Be + late K,M II star present remarkable optical spectra. Low velocity, dense winds from the late type star collide…

Discovery of metal-poor and distant pre-main sequence candidates in WLM with JWST

Venu M. Kalari, Ricardo Salinas, Morten Andersen +4

We present the discovery of twelve metal-poor and distant pre-main sequence (PMS) candidates in the dwarf irregular galaxy Wolf-Lundmark-Melotte (WLM)~968 kpc away, at a present-da…

A high-resolution imaging survey of massive young stellar objects in the Magellanic Clouds

Venu M. Kalari, Ricardo Salinas, Hans Zinnecker +3

Constraints on the binary fraction of young massive stellar objects (mYSOs) are important for binary and massive star formation theory. Here, we present speckle imaging of 34 mYSOs…
