Rogue Ones: Orbital census of Galactic Cepheids and their Anomalies
Shourya Khanna, Ronald Drimmel, Eloisa Poggio +2
Classical Cepheids (DCEPs) are excellent standard candles expected to trace the spatial and kinematic distribution of the Galaxy's young and dynamically cold stellar disc. Using th…
High-fidelity stellar extinction with Gaia and APOGEE -- I. The method and a new extinction curve
Jie Yu, Luca Casagrande, John A. Taylor +9
The scarcity of high-fidelity extinction measurements remains a bottleneck in deriving accurate stellar properties from Gaia parallaxes. In this work, we aim to derive precision ex…
The Effect of a Non-universal Extinction Curve on the Wesenheit Function and Cepheid Distances
D. M. Skowron, M. L. Fouesneau, R. Drimmel +1
The Wesenheit function is widely used to reduce the effects of interstellar reddening in distance measurements. Its construction, however, relies on the assumption of a universal e…
SpiralMap: A Python library of the Milky Way's spiral arms
Abhay Kumar Prusty, Shourya Khanna
We present a library of the major spiral arm models (and maps) of the Galaxy. The package is written in Python, and allows the user to both extract the 2D trace and overplot the sp…
C3PO IV: co-natal stars depleted in refractories are magnetically more active -- possible imprints of planets
Jie Yu, Yuan-Sen Ting, Luca Casagrande +14
Chemical abundance anomalies in twin stars have recently been considered tell-tale signs of interactions between stars and planets. While such signals are prevalent, their nature r…
The realm of Aurora. Density distribution of metal-poor giants in the heart of the Galaxy
Evgeny P. Kurbatov, Vasily Belokurov, Sergey Koposov +11
The innermost portions of the Milky Way's stellar halo have avoided scrutiny until recently. The lack of wide-area survey data, made it difficult to reconstruct an uninterrupted vi…
GaiaUnlimited: The old stellar disc of the Milky Way as traced by the Red Clump
Shourya Khanna, Jie Yu, Ronald Drimmel +9
We present an exploration of the Milky Way's structural parameters using an all-sky sample of RC giants to map the stellar density from the Galactic disc beyond 3 kpc. These evolve…
The Milky Way as Seen by Classical Cepheids II: Spiral Structure
Ronald Drimmel, Shourya Khanna, Eloisa Poggio +1
As a relatively young and bright population and the archetype of standard candles, classical Cepheids are an ideal population on which to trace the non-axisymmetric structure in th…
The Milky Way as Seen by Classical Cepheids I: Distances Based on Mid-infrared Photometry
Dorota M. Skowron, Ronald Drimmel, Shourya Khanna +3
Classical Cepheids are the archetype of the standard candle, thanks to the period-luminosity relation which allows to measure their intrinsic brightness. They are also relatively y…
