An Infant Sub-Saturn in Scorpius-Centaurus
Gurmeher Kathuria, Luke G. Bouma, Andrew W. Boyle +25
We report the discovery and validation of TIC 88297141 Ab, a transiting planet orbiting a pre-main-sequence M dwarf (0.31 solar masses, 0.74 solar radii) in the Scorpius-Centaurus…
Toddlers in Resonance I: low masses and eccentricities of the 17 Myr giant planets HIP 67522 bc from transit timing variations
Hannah R. James, Madyson G. Barber, Andrew W. Mann +28
Infant (100\,Myr) transiting planet systems provide glimpses into the processes that shape the observed mature planet population. Masses for these planets are powerful data poin…
A Detailed Spectroscopic Study of the WN6ha + O5 Colliding-wind Binary WR 25
Eric Gosset, Roberto Gamen, Laurent Mahy +3
Massive stars have a major impact on their environment in their host galaxy. Observational determinations of their physical parameters are required to better constrain evolutionary…
An Orbit for a Massive Wolf-Rayet Binary in the LMC: An Example of Binary Evolution
Breelyn Cocke, Philip Massey, Nidia I. Morrell +6
Wolf-Rayet (WR) stars are helium-burning, evolved massive stars which have had most of their hydrogen-rich outer layers removed either through stellar winds and/or binary stripping…
The Stellar Content of NGC~3603 Revisited: Is the IMF Top Heavy?
Philip Massey, Nidia I. Morrell, Kathryn F. Neugent +3
Studies of the resolved stellar populations of young massive clusters have shown that the slope of the initial mass function appears to be the same everywhere, with no dependence o…
A New Determination of the Mass of NGC 3603-A1: the Most Massive Binary Known?
Philip Massey, Sarah Bodansky, Laura R. Penny +2
The star NGC 3603-A1 has long been known to be a very massive binary, consisting of a pair of O2-3If*/WN5-6 stars, which show Wolf-Rayet-like emission due to their luminosities bei…
The Nature of a Recently Discovered Wolf-Rayet Binary: Archetype of Stripping?
Philip Massey, Kathryn F. Neugent, Nidia I. Morrell +2
LMCe055-1 was recently discovered in a survey for WRs in the Large Magellanic Cloud, and classified as a WN4/O4, a lower excitation version of the WN3/O3 class discovered as part o…
The Evolutionary Status of WN3/O3 Wolf-Rayet Stars
Kathryn F. Neugent, Phil Massey, D. John Hillier +1
As part of a multi-year survey for Wolf-Rayet stars in the Magellanic Clouds, we have discovered a new type of Wolf-Rayet star with both strong emission and absorption. While one m…
The Discovery and Physical Parameterization of a New Type of Wolf-Rayet Star
K. F. Neugent, P. Massey, D. J. Hillier +1
As part of our ongoing Wolf-Rayet (WR) Magellanic Cloud survey, we have discovered 13 new WRs. However, the most exciting outcome of our survey is not the number of new WRs, but th…
CAFÉ-BEANS: An exhaustive hunt for high-mass binaries
I. Negueruela, J. Maíz Apellániz, S. Simón-Díaz +11
CAFÉ-BEANS is an on-going survey running on the 2.2 m telescope at Calar Alto. For more than two years, CAFÉ-BEANS has been collecting high-resolution spectra of early-type stars w…
The HD5980 multiple system: Masses and evolutionary status
Gloria Koenigsberger, Nidia Morrell, D. John Hillier +5
New spectroscopic observations of the LBV/WR multiple system HD5980 in the Small Magellanic Cloud are used to address the question of the masses and evolutionary status of the two…
Southern near-infrared photometric monitoring of Galactic young star clusters (NIP of Stars)
R. Barbá, N. Morrell, G. Gunthardt +8
We have performed a near-infrared photometric monitoring of 39 galactic young star clusters and star-forming regions, known as {\em NIP of Stars}, between the years 2009--2011, usi…
