Discovery of the Magellanic Stellar Stream Out to 100 kpc

The Astrophysical Journal, 2023
The Magellanic Stream (MS)—an enormous ribbon of gas spanning 140° of the southern sky trailing the Magellanic Clouds—has been exquisitely mapped in the five decades since its discovery.

Magellanic Clouds Cepheids: Thorium Abundances [PDF]

Journal of Astronomy and Space Sciences, 2018
The analysis of the high-resolution spectra of 31 Magellanic Clouds Cepheid variables enabled the identification of thorium lines. The abundances of thorium were found with spectrum synthesis method. The calculated thorium abundances exhibit correlations

Optical spectra of radio planetary nebulae in the large Magellanic Cloud [PDF]

Serbian Astronomical Journal, 2008
We present 11 spectra from 12 candidate radio sources co-identified with known planetary nebulae (PNe) in the Large Magellanic Cloud (LMC). Originally found in Australia Telescope Compact Array (ATCA) LMC surveys at 1.4, 4.8 and 8.64 GHz and confirmed by

Runaway OB Stars in the Small Magellanic Cloud: Dynamical versus Supernova Ejections [PDF]

Astrophysical Journal, 2020
Runaway OB stars are ejected from their parent clusters via two mechanisms, both involving multiple stars: the dynamical ejection scenario (DES) and the binary supernova scenario (BSS).

CCD imagers for the Transiting Exoplanet Survey Satellite from benchtop to space environment

Astronomische Nachrichten, Volume 344, Issue 8-9, October-November 2023., 2023
Abstract The Transiting Exoplanet Survey Satellite (TESS) is a Massachusetts Institute of Technology‐led NASA Explorer‐class mission planned to spend 2 years discovering transiting exoplanets by an all‐sky survey. The observatory contains four wide field‐of‐view camera systems for a total of 16.8 Megapixel, low‐noise, low‐power CCD detectors.

An Unbiased CO Survey Toward the Northern Region of the Small Magellanic Cloud with the Atacama Compact Array. II. CO Cloud Catalog

The Astrophysical Journal, 2023
The nature of molecular clouds and their statistical behavior in subsolar metallicity environments are not fully explored yet. We analyzed data from an unbiased CO ( J = 2–1) survey at the spatial resolution of ∼2 pc in the northern region of the Small ...

LRO‐LAMP Lunar South Pole Cold Traps: Assessment of H2O and Potential CO2 and NH3 Reserves

Journal of Geophysical Research: Planets, Volume 128, Issue 8, August 2023., 2023
Abstract Nighttime Lyman Alpha Mapping Project (LAMP) observations are used to investigate condensed volatiles at the south polar region of the Moon. This study incorporates LAMP data from the first ∼7 years of the mission and Diviner annual maximum temperatures to search for volatile signatures associated with H2O, NH3, and CO2. Other stable potential
