The HASHTAG project I. A Survey of CO(3-2) Emission from the Star Forming Disc of M31
Zongnan Li, Zhiyuan Li, Matthew W. L. Smith +26
We present a CO(3-2) survey of selected regions in the M31 disc as part of the JCMT large programme, HARP and SCUBA-2 High-Resolution Terahertz Andromeda Galaxy Survey (HASHTAG). T…
Clustering of Local Group distances: publication bias or correlated measurements? VI. Extending to Virgo cluster distances
Richard de Grijs, Giuseppe Bono
We have established an internally consistent Local Group distance framework, using the Galactic Center, the Large Magellanic Cloud, and Messier 31 (M31) as important stepping stone…
Three-dimensional general relativistic Poynting-Robertson effect II: Radiation field from a rigidly rotating spherical source
Pavel Bakala, Vittorio De Falco, Emmanuele Battista +4
We investigate the three-dimensional, general relativistic Poynting-Robertson effect in the case of rigidly rotating spherical source which emits radiation radially in the local co…
The VMC Survey -- XXXV. Model fitting of LMC Cepheid light curves
Fabio Ragosta, Marcella Marconi, Roberto Molinaro +10
We present the results of the light curve model fitting technique applied to optical and near-infrared photometric data for a sample of 18 Classical Cepheids (11 fundamentals and 7…
Hard X-ray Cataclysmic Variables
D. de Martino, F. Bernardini, K. Mukai +2
Among hard X-ray Galactic sources detected in the Swift and INTEGRAL surveys, those discovered as accreting white dwarf binaries have suprisingly boosted in number in the recent ye…
Influence of Wolf-Rayet stars on surrounding star-forming molecular clouds
T. Baug, Richard de Grijs, L. K. Dewangan +5
We investigate the influence of Wolf-Rayet (W-R) stars on their surrounding star-forming molecular clouds. We study five regions containing W-R stars in the inner Galactic plane ($…
The VMC Survey -- XXXIV. Morphology of Stellar Populations in the Magellanic Clouds
Dalal El Youssoufi, Maria-Rosa L. Cioni, Cameron P. M. Bell +11
The Magellanic Clouds are nearby dwarf irregular galaxies whose morphologies show different properties when traced by different stellar populations, making them an important labora…
The intrinsic reddening of the Magellanic Clouds as traced by background galaxies -- I. The bar and outskirts of the Small Magellanic Cloud
Cameron P. M. Bell, Maria-Rosa L. Cioni, A. H. Wright +16
We present a method to map the total intrinsic reddening of a foreground extinguishing medium via the analysis of spectral energy distributions (SEDs) of background galaxies. In th…
Stellar rotation bifurcation caused by tidal locking in the open cluster NGC 2287?
Weijia Sun, Chengyuan Li, Licai Deng +1
We present a detailed analysis of the projected stellar rotational velocities of the well-separated double main sequence (MS) in the young, Myr-old Milky Way open cluster…
Tidal-locking-induced stellar rotation dichotomy in the open cluster NGC 2287?
Weijia Sun, Chengyuan Li, Licai Deng +1
Stars spend most of their lifetimes on the `main sequence' (MS) in the Hertzsprung--Russell diagram. The obvious double MSs seen in the equivalent color--magnitude diagrams charact…
Multiwavelength Period-Luminosity and Period-Luminosity-Color relations at maximum-light for Mira variables in the Magellanic Clouds
Anupam Bhardwaj, Shashi Kanbur, Shiyuan He +8
We present Period-Luminosity and Period-Luminosity-Color relations at maximum-light for Mira variables in the Magellanic Clouds using time-series data from the Optical Gravitationa…
2PBC J0658.0-1746: a hard X-ray eclipsing polar in the orbital period gap
F. Bernardini, D. de Martino, K. Mukai +2
The hard X-ray source 2PBC J0658.0-1746 was proposed as an eclipsing magnetic cataclysmic variable of the polar type, based on optical follow-ups. We present the first spectral and…
Extended main-sequence turnoffs in the double cluster and Persei: The complex role of stellar rotation
Chengyuan Li, Weijia Sun, Richard de Grijs +4
Using {\sl Gaia} Data Release 2 photometry, we report the detection of extended main-sequence turnoff (eMSTO) regions in the color--magnitude diagrams (CMDs) of the Myr-o…
Stellar rotation and the extended main sequence turnoff in the open cluster NGC 5822
Weijia Sun, Richard de Grijs, Licai Deng +1
The origin of extended main sequence turnoffs (eMSTOs) in intermediate-age (1-3 Gyr) clusters is one of the most intriguing questions in current star cluster research. Unlike the s…
When does the onset of multiple stellar populations in star clusters occur? Detection of enriched stellar populations in NGC 2121
Chengyuan Li, Richard de Grijs
Star-to-star light-element abundance variations, know as multiple stellar populations (MPs), are common in almost all Galactic globular clusters. Recently, MPs have also been detec…
Massive star cluster formation and evolution in tidal dwarf galaxies
Jeremy Fensch, Pierre-Alain Duc, Mederic Boquien +8
The formation of globular clusters remains an open debate. Dwarf starburst galaxies are efficient at forming young massive clusters with similar masses as globular clusters and may…
An intuitive 3D map of the Galactic warp's precession traced by classical Cepheids
Xiaodian Chen, Shu Wang, Licai Deng +3
The Milky Way's neutral hydrogen (HI) disk is warped and flared. However, a dearth of accurate HI-based distances has thus far prevented the development of an accurate Galactic dis…
The three-dimensional general relativistic Poynting-Robertson effect I: radial radiation field
Vittorio De Falco, Pavel Bakala, Emmanuele Battista +3
In this paper we investigate the three-dimensional (3D) motion of a test particle in a stationary, axially symmetric spacetime around a central compact object, under the influence…
