乌鸦座是南天小星座,属公元二世纪天文学家克劳狄乌斯·托勒密划定的48个星座,拉丁语原名“Corvus”意指乌鸦。希腊神话中乌鸦座的传说都与天神阿波罗有关。乌鸦座最亮的四颗恒星分别是軫宿一、軫宿三、軫宿二、軫宿四,在夜空构成显著的四边形。
2.59视星等的軫宿一是乌鸦座最亮恒星,是约四倍太阳质量的衰老藍巨星。历史短暂的左轄已有两个岩屑盤,三个恒星系有系外行星,可能还存在行星系但有待确认。乌鸦座TV是矮新星,由距离非常近的白矮星和棕矮星组成。
历史与神话
公元前至少1100年的巴比伦星表就把今乌鸦座范围恒星称为乌鸦(MUL.UGA.MUSHEN)。现代人更熟悉的古典天文学把乌鸦座放在蛇(九头蛇)尾处。巴比伦人用乌鸦座代表雨和风暴之神阿达德,进入第二个千年后会在秋天的雨季前夕上升。英国科学家约翰·罗杰斯(John H. Rogers)认为,长蛇座在古巴伦规范星表《纲要》代表冥界之神宁吉兹济达(𒀭𒊩𒌆𒄑𒍣𒁕)。他推断长蛇座旁边的巨爵座与乌鸦座都是死亡的象征,代表冥界之门。[1]乌鸦座、巨爵座、天鷹座和南魚座均在公元前500前左右传入希腊,分别代表冬至与夏至。此外,跨越全部天球赤道的长蛇座在古代还用作地标。[2]密特拉教的符号和标志里也有巨爵座与乌鸦座,估计该教源于中东,后传入古希腊和罗马[3]。
拉皮斯人传言阿波罗的情侣科洛尼斯偷人,阿波罗从纯白色的乌鸦口中得知后愤怒不已,把乌鸦的毛全变成黑色。还有说法称阿波罗派手下乌鸦去取水,但乌鸦在路上发现无花果后等待果实成熟再吃掉,因此延误行程。乌鸦用杯取水后顺便带回水蛇,谎称是水蛇喝掉水导致延误。阿波罗看出乌鸦的欺骗,愤怒之下把杯子、蛇和乌鸦都朝天上一扔,分别变成巨爵座、长蛇座和乌鸦座,所在位置正好确保乌鸦没法儿从杯里喝水,以此警告不要得罪神明。[4]
乌鸦座恒星在中国古代天文学属南方朱雀[5],四颗主要恒星构成二十八宿的轸宿星官轸,意为天车,右辖与左轄代表车轮支撑,长沙代表棺材[6]。印度天文学用乌鸦座五颗主要恒星代表二十七宿之十三诃莎多的手或拳头[7]。
众多玻里尼西亞文化把乌鸦座恒星划为星座。馬克薩斯群島把星座称为“米”(Mee),普卡普卡岛称为“蒂玛努”(Te Manu),社會群島称为“梅图艾帕帕”(Metua-ai-papa)。[8]。托雷斯海峡岛民把乌鸦座视为代表渔民的右手,组成巨大的“塔改座”(Tagai)[9]。
巴西中部马托格罗索州的波洛洛人把乌鸦座恒星看作陆龟“格里龟龟”(Geriguigui)[10],西北亚马逊地区的图坎诺人视为白鹭[11]。巴西聖路易斯島的圖皮人可能把乌鸦座星空视为用来烤鱼的烤架或烤炉,飞马座也可能代表烤架或烤炉[12]。
简介
乌鸦座覆盖184平方度夜空,占0.446%,在88个现代星座排第70[13]。星座北面和东面与室女座相邻,南挨长蛇座,西靠巨爵座。1922年,國際天文聯會确定以三字母缩写“Crv”代指巨爵座。[14]。比利时天文学家尤金·德爾波特1930年正式划分星座边界[注 1],乌鸦座呈六条边组成的多边形(见文首信息框)。星座在赤道坐標系統的赤经位于11h 56m 22s至12h 56m 40s范围,赤纬在−11.68°到−25.20°之间。[16]。星座位于南天球,北緯65度線以南才能看到完整星座[13][a]。
显著特点
恒星
德国天体制图师約翰·拜耳用希腊字母Α至Η为乌鸦座大部分亮星命名。約翰·佛蘭斯蒂德为九颗星体命名,但他划入旁边巨爵座HD 104337在1930年确定星座边界后纳入乌鸦座,即乌鸦座31。[17]乌鸦座共有29颗恒星亮度不低于6.5视星等[注 2][13]。
乌鸦座亮星軫宿三、軫宿一、軫宿二、軫宿四组成人称“角宿一后桅纵帆”[19]或“船帆”的四边形星群[20][21]。四颗恒星亮度都算不上出类拔萃,但因所在位置比较黯淡,星群在夜空很容易识别[22]。軫宿一与軫宿三指向角宿一,其中2.59视星等的轸宿一是乌鸦座最亮恒星[23]。该星又名“吉恩纳”(Gienah),意指“翼”[23],在拜尔《測天圖》上代表乌鸦的左翼[17]。轸宿一离地154±1光年[24],是光谱等级B8III的蓝白巨星,拥有+0.4
−0.3倍太阳质量 4.2[25],355倍太陽光度[23]。该星已有约+0.4
−0.3亿年历史 1.6[25],核心的氢基本耗尽并开始膨胀和冷却,脱离主序星阶段[23]。轸宿一是聯星,伴星是橙矮星或紅矮星,光谱等级K5V至M5V,质量约为太阳八成[26]。主星和伴星相隔约50天文單位[注 3],估计伴星围绕主星的公转周期是158年[25]。轸宿三是小型业余望远镜便能区分的雙星,2.9视星等的蓝白色主星距地球约87光年[24],约有2.7倍太阳质量,表面温度1.04万开尔文但光度却达太阳65到70倍,估计该星要么是仅320万年历史的年轻主序星,尚未进入稳定的主序星阶段;要么是2.6亿年历史的衰老星体,开始耗尽核心含氢并膨胀、冷却,在摆脱主序星阶段的同时辐射光度更强。星体光谱A0IV,与第二种情况相符。[27]轸宿三一号伴星周围发现温暖的星周塵,天文学通常把星周尘纳入恒星系[28]。二号伴星光谱K,是8.51视星等的橙矮星,周围也有星周塵。该星是后金牛T星,距主星至少650天文单位,公转周期至少9400年[29]。轸宿三又名“阿尔戈拉布”(Algorab),意为“乌鸦”[4],与另一颗星代表乌鸦的右翼[17]。联星斯特鲁维1669位于轸宿三东北4.5度,由相距5.4弧秒的两颗白色星体组成,可用小型业余望远镜分辨[30]。联星离地280光年,合并视星等5.2(肉眼可见),其中主星5.9视星等,从星6.0视星等[4]。
2.7视星等的轸宿四又名“克拉兹”(Kraz[31][17]),位于离地146±1光年的乌鸦胸口[24],约有2.06亿年历史,约3.7±1倍太阳质量,耗尽核心含氢后膨胀并冷却至表面温度5100开尔文,如今是光谱等级G5II的黄亮巨星[32]。估计轸宿四至今大部分时间是光谱等级B7V的蓝白主序星[33]。代表乌鸦鼻孔位置的轸宿二又名“明卡尔”(Minkar),离地约318±5光年[24],是光谱等级K2III的紅巨星,约有54倍太阳半径和930倍太阳光度[34]。该星质量约为太阳四倍,成型后大部分时间是光谱等级B5V的主序星[35]。光谱等级K1III的橙色衰老恒星轸宿增五位于四边形星群以南、轸宿二与轸宿四之间[22],光度约为太阳70倍[36],距地球331±10光年[24]。
光谱等级F1V的四等白色恒星右辖又名阿尔奇巴(Alchiba),离地48.7±0.1光年[24]。该星光谱以三天为周期变化,要么是光谱联星,但更可能是劍魚座γ型變星,如果确是后者,估计星体质量约为太阳1.39倍[37]。拜尔星图把右辖标在乌鸦的喙上方[17]。
除轸宿三外,光谱等级F2V的黄白主序星左轄也代表乌鸦右翼[17],质量为太阳1.52倍,光度4.87倍,距太阳系约59光年[38]。该星有两道岩屑盤环绕,其一相隔不到3.5天文单位,内部温度较高;其二相隔约150天文单位[39][40]5.21视星等的蓝白Be星长沙代表乌鸦颈部[17],与星体HR 4691相距七弧秒[41],距地球420±10光年[24],光谱等级B8V。光谱中的氢发射线表明该星有星周盤,可能是光学双星或多颗恒星组成的小星系,与主星相隔至少五万天文单位,公园周期至少350万年。HR 4691就是双星,主星是光谱等级K0或G3的衰老黄巨星,从星是F型主序星。[41]
佛蘭斯蒂德曾把5.26视星等的HD 104337划入巨爵座,人类一度以为它是水星的衛星。1974年3月27日,水手10號发现该星发射的远紫外线,表明星体属卫星,但后来发现是由恒星发出。[42][43]如今科学家已确定HD 104337是遥远的联星系,主星是光谱等级B1.5V的炽热蓝白星,对伴星暂时还不了解。两星以2.9631天轨道周期围绕彼此旋转,主星可能是畢宿星團的藍掉隊星[44],约有15.5倍太阳质量,光度更达52262倍[45]。
HD 110317又称乌鸦座VV,是间隔很小的光谱联星,围绕彼此旋转的轨道周期仅1.46天[46]。两者都是光谱等级F5V的黄白主序星,其中主星的主序星阶段即将结束,开始膨胀和冷却[47]。两星质量比0.775±0.024[48],2微米全天巡天在内部发现第三颗星体[49]。
