Nature has presented us with a gift of incalculable value: astounding diversity of plant and animal life and interwoven biological and physical systems of intricate complexity and beauty. We are faced today with an existential environmental and moral

The unusual properties of transition objects (young stars with an optically thin inner disc surrounded by an optically thick outer disc) suggest that significant disc evolution has occured in these systems. We explore the nature of these systems by e

We present the discovery of debris systems around three solar mass stars based upon observations performed with the Spitzer Space Telescope as part of a Legacy Science Program, ``the Formation and Evolution of Planetary Systems'' (FEPS). We also conf

We summarize the results of an observing campaign to identify periodic pre?main-sequence (PMS) variables in the NGC?2264 OB association. We find 201 periodic candidates. The mean age of the NGC?2264 periodic variables is approximately 30% greater tha

We present HST/NICMOS observations with 0.1" (15 AU) resolution of six young stellar objects in the Taurus star-formation region. The targets of our survey are three Class I IRAS sources (IRAS 04016+2610, IRAS 04248+2612, and IRAS 04302+2247) and thr

We combine our previous optical spectroscopic and photometric analysis of ~1600 stars located in the Orion Nebula Cluster (ONC) with our own and published near-infrared photometric surveys of the region in order to investigate the evidence for and pr

Models for the thermal emission from dusty infalling envelopes around protostars indicate that the envelope emission can greatly exceed the stellar plus disk photospheric emission at wavelengths ~2 μm. We argue that this thermal envelope emission ac

We present estimates of the binary frequency for optically visible (IHST < 19 mag) members of the dense (mean star separation ~0.05 pc) embedded stellar clusters associated with NGC 2024, NGC 2068, and NGC 2071 (distance = 460 pc) based on Hubble Spa

We report the results of a study of the intermediate and high mass stars in the young, rich star-forming complex IC 1805, based on a combination of optical, near-infrared, and mid-infrared photometry, and classification spectra. These data provide th
