(EDP Sciences, 2011-06)A series of 353 red electronic spectra (from three observatories, mostly from 6300 to 6700 A) obtained between 1994 and 2010, and of 171 UBV photometric observations (from two observatories) of the 2010 eclipse, were ...

(Elsevier, 2008)The ground state structure of [superscript 9]Li has been investigated through the d([superscript 9]Li, t)[superscript 8]Li one-neutron transfer reaction at E/A = 1.68 MeV. The [superscript 8]Li sub-system in [superscript ...
-
(Royal Astronomical SocietyOxford University Press, 2011-06)We present measurements of the specific star formation rate (SSFR)–stellar mass relation for star-forming galaxies. Our deep spectroscopic samples are based on the Redshift One LDSS3 Emission line Survey (ROLES) and European ...
-
(American Physical Society, 2015-03-04)Background: In the absence of accurate data on the free two-body hyperon-nucleon interaction, the spectra of hypernuclei provides information on the details of the effective hyperon-nucleon interaction. Purpose: To ...

Spectroscopy, MOST photometry, and interferometry of MWC 314: is it an LBV or an interacting binary? (Oxford University Press, 2016)MWC 314 is a bright candidate luminous blue variable (LBV) that resides in a fairly close binary system, with an orbital period of 60.753 [plus or minus] 0.003 d. We observed MWC 314 with a combination of optical spectroscopy, ...

Stable and unstable accretion in the classical T Tauri stars IM Lup and RU Lup as observed by MOST (Oxford University Press, 2016-03-11)Results of the time variability monitoring of the two classical T Tauri stars, RU Lup and IM Lup, are presented. Three photometric data sets were utilized: (1) simultaneous (same field) MOST satellite observations over ...
-
(Oxford University Press, 2014-10-11)We present an analysis of the 2011 photometric observations of TW Hya by the MOST satellite; this is the fourth continuous series of this type. The large-scale light variations are dominated by a strong, quasi-periodic ...
-
(American Astronomical Society, 2013-12)A group of suspected protostars in a dark cloud northwest of the young (∼2 Myr) cluster Berkeley 59 and two sources in a pillar south of the cluster have been studied in order to determine their evolutionary stages and ...
-
(American Astronomical Society, 1997-09)The central region of the Monoceros R2 molecular cloud has been studied using molecular line maps, maps in continuum emission, and an M-band (4.7 [micrometres]) absorption spectrum toward Mon R2 IRS 3. Maps were made in ...

Stars, dust, and the growth of ultraviolet-selected sub-L[superscript ∗] galaxies at redshift z ∼ 2 (Oxford University PressRoyal Astronomical Society, 2012)This work concerns the physical properties of very faint (R[subscript lim] = 28 AB mag; M[subscript stars,lim] ∼ 10[superscript 8] M[subscript circled dot]), ultraviolet-selected (UV-selected) sub-L[superscript ∗] BX ...
-
(Royal Astronomical Society, 2012-12)By means of high-resolution cosmological hydrodynamical simulations of Milky Way (MW) like disc galaxies, we conduct an analysis of the associated stellar metallicity distribution functions (MDFs). After undertaking a ...
-
(American Astronomical Society, 2005-12-10)Eight consecutive low-frequency radial p-modes are identified in the G0 IV star [eta] Bootis based on 27 days of ultraprecise rapid photometry obtained by the MOST (Microvariability and Oscillations of Stars) satellite. ...
-
(Oxford University Press, 2016-05-11)Binary stars provide a valuable test of stellar structure and evolution, because the masses of the individual stellar components can be derived with high accuracy and in a model-independent way. In this work, we study ...
-
(American Astronomical SocietyIOP Publishing, 2010-09-10)We present a study of a stellar population of Ly[alpha] emitters (LAEs) at z = 4.86 in the Great Observatories Origins Deep Survey North (GOODS-N) field and its flanking field. The LAEs are selected based on optical ...
-
(American Astronomical SocietyIOP Publishing, 2009-03-01)We present the results of spectral energy distribution (SED) fitting analysis for Lyman break galaxies (LBGs) at z ∼ 5 in the Great Observatories Origins Deep Survey North (GOODS-N) and its flanking fields (the GOODS-FF). ...
-
(American Astronomical SocietyIOP Publishing, 2009-05-20)Accretion disk reflection spectra, including broad iron emission lines, bear the imprints of the strong Doppler shifts and gravitational redshifts close to black holes. The extremity of these shifts depends on the proximity ...

(EDP Sciences, 2012-01)Approximately 14% of known Galactic open clusters possess absolute errors ≤20% as evaluated from n ≥ 3 independent distance estimates, and the statistics for age estimates are markedly worse. That impedes such diverse ...
-
(Springer Nature, 2017-10-17)Vegetation structure, defined by the height, cover, and types of plants, is an important component of habitat suitability for plant species or communities. The identification of potential habitat is a crucial knowledge gap ...
-
(Finnish Society of Forest Science, 2015-06-11)Natural disturbances such as insect outbreaks create boundaries that influence vegetation patterns and ecological processes. To better understand the effects of natural edge creation on relatively intact forests and ...
